What is TCP/IP?

Nobody can deny how amazing the Internet is! But it’s the result of a lot of developments and smart creations. So every time it improves somehow, the reason is, a technology or group of technologies behind it have really achieved the next level. 

What is TCP/IP?

TCP/IP is a combination of two protocols, the Transmission Control Protocol and the Internet Protocol. It is a set of rules that are crucial for everyone involves to communicate within and across networks. 

TCP/IP determines how data is communicated by deciding the way they have to be chopped into different packets for being addressed, routed, transported, and delivered.

TCP is in charge of securing the data integrity during their trip that starts when they are sent and finishes when they are received in their proper destination. TCP functionality organizes data for preserving them while the communication client-server is on. 

IP marks the formats and conditions for establishing the communication and the data packets exchanged between devices and applications on a network.

IP addresses and routes data packets originated in a source to deliver them to their right destination.

Besides, machines can’t connect to networks nor exchange data with other connected machines without having a unique IP address for being identified.

TCP/IP is a stateless suite. Therefore every request from a client is considered a new one since it’s not linked to previous requests. This is a way to make the paths on the network free for constant use.

How does it work?

TCP is a connection-oriented protocol. An active connection between the source and the receiver is a key requirement for fulfilling the process from the beginning (sent) to the end (delivery). 

Once this requirement has complied, TCP chops into packets the message originated on the source. Then TCP gives a number to each of those packets to preserve the integrity of the whole message. Now, packets are ready to go to the network layer (IP) for being transported. The way to their destination will push them through different gateways, routers, and even different paths. Yes! All packets belonging to one message but, while separated, they can be routed differently. In the end, they have to arrive at the same spot.

Once this happens, TCP rebuilds the message, following the numerical order of all packets, to deliver it. And here, the process gets completed.

That is the ideal scenario, but packets can face problems during their trip. As a result, some of them can get lost, duplicated, or disordered. Fortunately, TCP’s functionality can sort out such problems. For instance, it can ask the missing packets to be sent again. Then, the message can be rebuilt correctly.

TCP/IP advantages.

  • Everybody can use it. It’s an open protocol.
  • It’s not heavy. It doesn’t mean a strain that can affect your network or hardware. 
  • It supplies the IP addresses that machines need to be identified (security) and connected to. 
  • It allows the connection of different kinds of devices without problems.
  • It supports communications across different networks.
  • It doesn’t depend on the operating system for working.
  • It allows scalability. You can add the extra networks you need.
  • It supports different routing protocols.

TCP/IP disadvantages.

  • It has vulnerabilities that cybercriminals can use.
  • It suits large networks, not PAN or LAN.
  • It’s hard to replace the protocols included in the suite.


We usually admire only the tip of the iceberg, but the Internet wouldn’t be possible without the contribution of every part of its massive machinery. And TCP/IP is a key gear on that machinery! 

What is the purpose of TTL?

Time is a factor permanently present in our lives. It can be stressful, but it’s an efficient way to organize and control different aspects. The idea of chaos sometimes sounds exciting, but being realistic, it’s not viable when it’s about keeping a network running smoothly. That’s why TTL exists!

What’s TTL?

TTL, or time-to-live, is a mechanism to define the period of time for data to keep living, meaning being valid, stored, or to keep traveling on computers or networks. Once the TTL value defined by the administrators to those data expires, they get discarded.

Data packets have a place for the TTL value to be registered. Once that value is established, it can be readable by routers and other machines.

What is the purpose of TTL?

The purpose of TTL is to limit the time for data packets to be traveling around machines, applications, or networks.

Data packets are constantly traveling across the Internet. Without a mechanism to control them, in a few years, the traffic could be chaotic. The first data packet ever sent could still be traveling around!

A limited time clearly established on data packets helps routers not to have them around permanently. Besides, time-to-live helps to obtain essential information from data packets. For example, you can know the time a data packet has been traveling within a network and its complete route.

Sources send data packets for being delivered to specific destinations. While traveling, they touch different points on the network called hops. Routers receive data packets and read their TTL. If this lecture shows the packets still have time/hops to travel, they will be pushed to the next point. But if their time-to-live is expired, packets will be discarded. 

Routers will report the situation to the data source via an ICMP message. ICMP (Internet Control Message Protocol) messages are a resource to diagnose and inform errors. An ICMP message will be sent to the IP address of the source that emitted the discarded packet. 

An ICMP message dispatched by a router to report the TTL expiration of a packet will take a specific time to reach its destination, the packet’s source. Considering that time, the hopes that the packet touched when its TTL was still valid can be tracked. You can track its complete route!

Where can you find TTLs?

  • In networking, you can find TTL in every data packet sent online to deliver to a recipient.
  • DNS queries are also data packets. Therefore they have time-to-live.  
  • Content delivery networks (CDN) use the TTL to set up the time for their servers to cache the content they distribute. When the time-to-live expires, that content is discarded. Servers have to query primary servers to update and get a new copy to cache it until the TTL expires again. 
  • DNS recursive servers cache DNS records, the time defined in every record. Each has its own TTL. When it expires, the recursive server has to get a new copy of the record from the authoritative DNS server to cache it again.

Benefits of TTL.

  • It contributes to keep systems under control and reducing stress on them by enhancing the performance of caching.
  • CDNs are really big networks. Time-to-live helps them hold copies of the content they distribute, time enough not to be stressed with continuous requests from primary servers. 
  • The consequent reduction of bandwidth and faster serving are not minor benefits!


TTL is a mechanism that proves that time totally matters!

​FTP vs HTTP – differences

Have you ever thought about the differences between FTP vs HTTP, and why do we use HTTP for the World Wide Web? Now you will have your answer. 

​What is FTP?

FTP stands for File Transfer Protocol, and it is a protocol that allows file transfer between two different hosts (devices) using the TCP/IP protocol. It is using the client-server model, where one of the hosts is called a remote host (server) and needs FTP software to be a server, and the other is called a local host (client) with FTP client’s software. Both of them need to be connected and configure to use the FTP protocol for communication.

​FTP is used for:

  • Downloading some files over the Internet.
  • Downloading or uploading files on a web hosting.
  • Other types of communication.

​What is HTTP?

HTTP stands for Hypertext Transfer Protocol, and it is a protocol that we use on the Internet (World Wide Web) for loading pages through hyperlinks. It also uses the same client-server model as the FTP, where a client sends a request and the server answer with the requested content or action. The most common HTTP requests are GET, to get a particular resource, and POST, which indicates to post the text or file.

​HTTP is used for:

  • Navigating the Internet.
  • Downloading or posting on the Internet.
  • Communication between client and server.
  • Communication between servers.

​FTP vs HTTP comparison

Let’s get into the details, how similar and how different FTP vs HTTP are. You will be surprised how much in common the two network protocols have.

  • Both FTP and HTTP are network protocols.
  • Both FTP and HTTP have their secure versions that use data encryption – FTPS and HTTPS.
  • Both FTP and HTTP are still used on the Internet.
  • Both FTP and HTTP can be used for file transfer on the Internet.
  • Both FTP and HTTP use the TCP protocol but different ports.
  • Common ports for FTP are port 20 and port 21, while HTTP uses port 80 and port 8080.
  • FTP is for file transfer from a remote host after a connection is established, and HTTP is for web browsing after a connection is established.
  • FTP is usually slower than HTTP because HTTP can download a file in chunks and speed up the transfer. Also, the FTP needs to re-establish the connection between each file if there are multiple files, and that will cost extra time.
  • FTP can be used via a program, user interface, or a command-line interface, while HTTP is used through a web browser application.
  • FTP requires authentication (user name and password), while HTTP does not require authentication.
  • HTTP supports sending and receiving multiple files, while FTP does not support multiple files simultaneously.
  • HTTP provides metadata, and FTP does not.
  • FTP uses two connections at a time, while HTTP uses only one.
  • HTTP uses persistent connection (keep the connection going) for a longer time and multiple files, while the FTP needs to start and finish a new connection per each file.
  • Both FTP and HTTP support IPv6.


Both FTP and HTTP have a lot of similarities. They are still in use, and they have their secured versions. But, the biggest difference between them is their purpose. FTP is very limited and servers only for file transfer, while HTTP and its work make it irreplaceable for web browsing.

Understanding Internet Protocol Version 4 (IPv4)

IP address – What is it?

The IP (Internet Protocol) address helps with identifying most of the elements inside a network. Each device, laptop, computer, smartphone, etc., requires an IP address to successfully connect to a private network. Also, when we are talking about connecting to the Internet, we have the same case. The user is receiving a public IP address provided by an Internet service provider (ISP). For the purpose of operating accurately, servers also have a public IP address.

Thanks to IP addresses, the Internet is able to recognize different participants, devices, which every communication contains. The IP address also gives its location in the network. That makes the machines available to exchange data and communicate.

IPv4 explained.

IPv4 is short for Internet Protocol version 4. It is represented with a numerical string composed of four groups. Each group contains a number between 0 and 254, and they are separated by dots. It is a 32-bit address. For example, IPv4 looks like:

This version of the IP address is a connectionless protocol. That is the reason why it doesn’t need a prior adjustment between the two endpoints for the connection to operate successfully. To make it simple, devices are able to send data to a recipient and don’t have to check if it is available first. 

IPv4 determines addresses, packets’ format, and routes data. On the networks, a lot of data is communicated every second. If those data are too big to be carried to their destination, IPv4 is capable of detecting that. So with the help of Transmission Control Protocol (TCP), the data is divided into smaller pieces and is easier to transport. Also, on every data packet is going to be written the IP address of their destination, and their route is also set. So until they reach their target, they are going to travel through nodes, routers, etc. 

If devices want to connect to a network and be able to use its resources, they need IPv4 addresses. That way, with the implementation of IPv4, they can be successfully located and identified on a network.

No matter IPv4 was first described in 1981, it is still a very commonly used IP version. The newer version and future replacement is the IPv6. It is already in use, and it is operating accurately. However, achieving the whole transition from IPv4 to IPv6 requires more time.  


IPv4 addresses are simpler, and their structure includes fewer numbers. On the other hand, the new version of IPv6 has a more complicated format. This matters when we are talking about manual tasks. With IPv4, the possibility for human mistakes is way more reduced.   

The compatibility of IPv4 is much more extensive. Both the older and newer systems support this version of Internet Protocol without any problems. On the other side, version 6 of the IP address is supported only by most modern devices.

The topology is a lot easier and simpler to be applied on networks.

What is Cloud Computing?

Cloud computing is the distribution of different computing services or resources (storage, networking, analytics, software, intelligence, servers, disaster recovery technology, security, etc.) through the Internet.

Cloud computing changed the model of hiring these services. Clients don’t have to buy, own and maintain data centers and servers. Instead, they can have access to the specific services they require on-demand. As a result, clients’ operation costs can be lowered, and they can access an efficient and modern infrastructure.

Benefits of cloud computing.

  • Efficient your budget. Cloud computing supplies the necessary infrastructure without you purchasing hardware, *software (*in some cases), servers, data centers, maintenance, etc.  
  • Easy access to top-notch technology. There is a wide variety of technologies available for you to access and boost your business. In addition, the price will probably be lower than if you buy them because their cost is shared by different clients. 
  • Fast deployment. No matter the geographical location of your business’s branches, the software can be deployed worldwide in just minutes. Your application or service can get the necessary infrastructure to be available globally. To be close to your potential clients around the world is possible. 
  • Scalability. To calculate the resources you will need in the future, provisioning resources in case of peak activity levels is not that crucial on the cloud. You can simply get and pay what you need today (bandwidth, storage, computing power, etc.), during peak activity moments, and so on. You can go up or down in demand for services.
  • Security. Trustable cloud providers have policies, guarantees, advanced technology, and controls to strengthen your security, protect your data, applications, etc., from threats. A team of hundreds of IT specialists of the cloud provider can defend a lot better your server than your company’s IT team of a few people.   
  • Trustability. Cloud providers have a robust infrastructure and redundancy enough to offer you an efficient backup, disaster recovery, guarantees for their services, etc. 
  • More productivity. Cloud computing solves many of the daily tasks IT teams manage (maintenance of software, hardware, patching, updating, etc.). Your collaborators can invest this time in key projects and the development of your business.

Types of cloud computing.

Cloud computing services are generally divided into three categories. Infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Let’s check them out!

  • Infrastructure as a service (IaaS). What it supplies you it’s the necessary IT infrastructure to run your business. Virtual or dedicated hardware (virtual machines or servers), operating systems, storage, networks, etc. it offers a high level of flexibility and control over the IT resources. You pay for every resource as long as you use it.
  • Platform as a service (PaaS). These are the type of cloud computing services that provide you the environment you need for designing, creating, testing, managing, and delivering software applications. Developers don’t have to get servers, storage, databases, network, etc., required for their work. 
  • Software as a Service (SaaS). It offers you a vast menu of software applications delivered through the Internet, on-demand. SaaS providers host, maintain (update, upgrade, patch, fix errors, etc.), and manage the software for you. Clients only have to connect to the application they require through a common browser or application, no matter their location or device (computer, tablet, phone, etc.). 


Cloud computing makes things easier for business owners like you. The money and time it saves you makes it a choice to be considered. Define clearly your business needs to choose the type of service that suits you better.

Error 404 explained

Pretty much all the time, there’s an interaction between the browsers and servers. This communication is triggered every time someone in the world requests a website. Servers have their own way of informing the status of that request: the HTTP codes. There are five HTTP code categories. Statuses are expressed through three numbers. The first number indicates the type of status.

  • 1XX, informational responses.
  • 2XX, successful responses.
  • 3XX, redirects.
  • 4XX, client errors (like error 404). 
  • 5XX, server errors.

What is error 404?

Error 404 means “not found”. It is a type of HTTP response status code that points to the category of “client errors”. 

That “not found” status can mean:

  1. The requested resource can’t be found on the server.
  2. Talking about a browser, it means the requested URL can’t be found.
  3. In APIs (application programming interfaces), even if the endpoint is valid, the resource is not available anymore. 

For sure, you have seen error 404 different times while surfing online. The reason is the Internet has a really big amount of broken or dead links. So every time someone clicks one of those dead/broken links, the error 404 message is shown.

This code only points that the requested resource is not found, but it does not supply additional information to understand if this resource’s lack of availability is temporary or permanent. 

Error 404 format.

This status code can be shown as follows.

  • HTTP 404 Not Found
  • 404 Page Not Found
  • Status 404 Not Found 
  • 404 Not Found Error 
  • 404 File or Directory Not Found
  • The requested URL was not found on this server

How can you repair error 404?

Detect broken links. Your website can have internal or external links causing error 404. You can check them manually or through a software tool. Once found, fix them or delete them.

Talking about internal links, it’s not rare people mistake while typing URLs, and typos produce broken links. Articles placed in incorrect categories can drive to broken links too.

External links are useful to give examples, to recommend content, etc. The problem is, they all belong to different websites, and they can be deleted or relocated by the owners without you knowing about the change. Check external links regularly. Delete the ones that don’t work or replace them with others that work properly. 

Be careful while deleting content. Sometimes, some pages are deleted during maintenance or renovation of websites, but the links that point to them remain. These become broken links. 

Redirect properly. While organizing websites, the change of URL for certain pages (content) is a common action. But if you don’t redirect your audience correctly, they can be clicking a dead link.

Customize Error 404. To have an error 404 is always a possibility. Prepare in advance! Customize your error page to apologize and not to lose your audience. As users, we all get annoyed when we request content, and instead, we receive an error answer with a code we don’t necessarily understand. Make this page useful, informative for users to know what’s going on.


Error 404 is common, but you can track its causes to repair the pages manually or with software’s help. Prevent it as a part of your website maintenance before it affects your users’ experience, and bounce rating. Broken links affect the SEO, and you don’t want to harm your search ranking, do you?

What is Enterprise DNS?

Enterprise DNS (domain name system) is a high-level DNS service specially focused on large enterprises with big needs. Enterprise DNS implementation offers to resolve internal and external requests for enterprises in an efficient, scalable, secure, automatable, and centrally managed way. Enterprises need a reliable DNS architecture to operate, bullet-proof security, redundancy, speed, 100% uptime… and more capabilities that domain registrars’ DNS can’t guarantee exclusively for a single client.

Enterprise DNS means the opportunity to have a robust DNS architecture (network, DNS servers) and all its capabilities, for your organization, totally at your service. 

It’s a really powerful solution for companies that already have a complex and hard-to-manage structure. They have grown international, and they have plenty of branches, which means regular DNS modifications, implementation of new technologies, re-configurations, scalability at a high level, etc. 

When do you need Enterprise DNS?

  • You need it when your business has grown in such a dimension that you have to operate expeditiously big actions like the following. 
  • To have 100% DNS availability to guarantee access and to handle all the traffic.
  • To attend millions of DNS requests every month. Usually, with regular DNS service providers, clients have a limit of requests that can be attended per month. This limit and the extra fees you have to pay in case you cross it don’t exist with enterprise DNS. 
  • To automate thousands of modifications to the DNS configuration every hour.
  • To count on the fastest propagation. Enterprise DNS supplies the possibility of managing and monitoring the propagation via the control panel. TTL values can be modified (up to a minute) from there to accelerate propagation. 
  • To manage thousands (or more) of IP addresses with 100% uptime.
  • To rely on high speed for responding to clients’ requests globally. Enterprise DNS providers offer a robust network with servers strategically located for you to be really close to your clients.
  • To turn on/off thousands of virtual machines every hour.
  • To manage the connection for thousands or millions of IoT (Internet of things) devices.
  • To enable a virtual network for DHCP (dynamic host configuration protocol) services across many different locations.
  • To have a centralized, clear, detailed view of the inside DNS traffic of your enterprise. Meaning, traffic is generated by thousands of collaborators, machines, and branches.
  • To reduce notoriously human errors through automation.
  • To strengthen your security defenses on a large scale, detect threats expeditiously (close to immediately), and be protected in case of DDoS (distributed denial of service) attacks.
  • To rely on 24/7 customer service for your operation and your clients’ not be stopped.

Who is using Enterprise DNS?

Enterprise DNS is already being used by international e-commerce shops that have to attend a really big number of global requests every minute. 

Enterprises offering business applications. They provide the software for every employee to work daily in different companies/industries. They can’t afford outages or downtime. That would mean stopping the productivity and incomes of complete companies.

Enterprises supplying mission-critical applications. They work with highly resource-demanding companies. Internet providers, data centers, hosting providers, aircraft or railway operating systems, electric power grid systems, online banking systems, etc.


Enterprise DNS is a massive solution for massive enterprises’ needs. The whole Internet relies on such infrastructure. Imagine having your own! It goes far beyond the regular imagination!

SaaS vs PaaS vs IaaS – What is the difference?

Today we are going to talk about Cloud Computing. It is the practice of using outside servers that are connected to the Internet for storing data, managing the data, information processing, and other tasks. The most popular types of Cloud Computing are SaaS, PaaS, and IaaS. Let’s see the differences. 

Local server

When you have your own server hosted on-site, you will be responsible for all of the following categories: 

  • Networking. Here you will need the Internet, routers, and all the connection between the devices. 
  • Storage. Storage for hosting data. 
  • Servers. The computers that will offer services. 
  • Virtualization. A way to offer virtual machines. 
  • OS. An operating system like Windows, Linux, etc. 
  • Middleware. Drivers for devices, APIs, application services, etc. 
  • Runtime. – frameworks and environments for developers and services needed for other applications. 
  • Data. – data storing and processing. 
  • Application. Software that will be used for the needs of the company. 

We need this information for the basis of our comparison of SaaS vs PaaS vs IaaS and to understand better the differences. 


SaaS is a software as a service. When we talk about SaaS, the client gets directly a software to use. He or she can’t modify the software and gets features based on the plan that he or she has chosen.

The SaaS provider is responsible for all of the previously mentioned categories – networking, storage, servers, virtualization, OS, middleware, runtime, data, and application. The provider must take care of bug fixing, errors, software updates, and adding new features.

Advantages: easy to start, easy to use, no maintenance needed.

Disadvantages: zero control over the software and its development, vendor lock-in that makes it harder to migrate to another,

Typical examples of SaaS are Dropbox, Microsoft 360, Skype, etc.


PaaS is a platform as a service. PaaS is a good choice for development. It offers everything already up and running, including networking, storage, servers, virtualization, OS, middleware, and runtime. 

The developers can jump to the action and start writing code right away. The client will need to take care of the data and the applications that will be needed.

Advantages: almost everything is pre-installed, so you can choose what applications do you need and start using them. You don’t take care of the infrastructure or OS.

Disadvantages: the storage is still the provider’s responsibility, so it can’t be 100% secured, which might be more expensive than an IaaS solution.

Typical examples of PaaS are Microsoft Azure, Amazon AWS, Google Cloud, etc.


IaaS is infrastructure as a service. In the case of IaaS, you will get an open canvas. The IaaS provider will take care of the infrastructural part – networking, storage, servers, and virtualization. 

The client takes care of OS, middleware, runtime, data, and applications.

It is a great next step when you want to stop worrying about the on-premise server and go to the cloud.

Advantages: you forget to worry about infrastructural problems of your server, pay-as-you-go model, cheaper to start than a local server.

Disadvantages: You still have many things to take care of, a lot more than in the case of PaaS or SaaS. You will need to maintain the system and the software.

Typical examples of IaaS are Rackspace, Amazon AWS, Microsoft Azure, Google Cloud, and many smaller providers.


SaaS is the easiest to manage from the client’s perspective. PaaS is a great option for creating development servers, use and create applications. IaaS is the most basic cloud approach, but it has the highest freedom for the client.

What is IPAM, and why is it important?

What does IPAM mean?

IPAM is short for IP Address Management. It is a method of IP scanning and IP address tracking. It manages the data correlated with a network’s Internet Protocol address range and IPAM system. As a result, administrators are able to guarantee that the list of assignable IP addresses is up to date and enough with IPAM software and IP tools. It comes to make things simple and automates the management of many duties for maintaining IPs. With the IPAM network, are also common functionalities, such as managing reservations in DHCP, reporting, and data collection.

How does it work?

IPAM assists with numerous tasks, and each has its own process. As a result, there can be variations in the technical way they work.

It handles three essential things in every network: IP addresses, Domain Name System (DNS), and Dynamic Host Configuration Protocol (DHCP). They produce fundamental data for IPAM to accomplish its tasks.

To receive details from all your network’s devices, IPAM uses Internet Control Message Protocol (ICMP), Simple Network Management Protocol (SNMP), and neighborhood scanning. SNMP is capable of collecting and organizing information about IP networks’ devices. 

With the combination of such tech and further monitoring tools, IPAM is able to receive the needed information to control the IP address range o your network. The whole statistics and information is saved in a database and can be easily accessed.

IPAM combination with DNS and DHCP

Administrators who manage DNS and DHCP services can benefit from IPAM. IPAM tools can be effective on their own, but they can’t solve alone underlying problems frequently associated with decentralized network based systems.

If you apply IPAM software on its own, the absence of integration with DNS and DHCP can be a problem. This is because these core networks roles are strongly tied to each other. If you want your IPAM data much more accurate, keep DNS and DHCP data synced. It would be a lot more valuable that way.

Operating without it

You can operate without IPAM, but it will be more challenging. The IT team can handle a small network with a simple spreadsheet. It will contain a table of IPs, routers, connected devices and port numbers. For a bigger network, this way of managing will be very problematic. It will be the admin’s job to check the extensive number of IPs and constantly will have to update the spreadsheet.

Here are some of the problems that probably will occur:

  • Troubleshooting difficulties. Everything is more complicated when it has to be done manually. Discovering the specific network issue can be a nightmare. It could take a lot of valuable time.
  • Safety problems. The chance for security breaches is very high. An unrecognized new device can connect to the network when the accountability is not well done.
  • IP address struggle. IP conflict is a possible scenario if there is no well-configured DHCP, and the admin is doing it manually. If two machines receive the same IP, neither one will be able to connect. If one of the devices is a server, this would surely be annoying.
  • Compliant problems. You might need reports and logs for your IP address space. It depends on the country you are in. If you are required to provide a report, it has to be proper.

What is Premium DNS service?

Whether you own a personal blog or a big e-shop, you have to use a DNS service to be reachable online. Premium DNS service is paid, but the benefits of using it are numerous. So let’s explain a little bit more about it.

Premium DNS explained 

Premium DNS is a service, which provides excellent features. It helps your site to operate smoothly. This service guarantees so much more than a free service. So what can you expect from it? It includes:

  • More DNS zones. 
  • Higher speed.
  • Faster loading time.
  • Strong DNS servers’ networks. Benefit from a lot more presence points (PoP) for your business.
  • Load balancing methods, including GeoDNS
  • Uptime is guaranteed.
  • Friendly and simple interface.
  • Millions of queries, and often unlimited amount.
  • Effectively managing the traffic.
  • DNSSEC support, monitoring, and checkings
  • Cryptographic and excellent tech security to keep your site protected from vulnerabilities and attacks. You can get more or less features, depending on the plan you choose. 
  • DNS failover.
  • More email forwards.
  • 24/7 Professional support.

What is DNS?

It is proper to explain what DNS is. So, it will help to understand the whole picture about Premium DNS fully. 

In brief, DNS is a global network of name servers. It has the primary purpose to show where are the domain names are really. In addition, the Domain Name System helps to link the domain names to their IP addresses. It is easier for humans to remember the name of a particular website rather than all IP addresses for all sites, which they use regularly.

Moreover, the Domain Name System has features, such as linking hostnames to other hostnames, verifications, and further instructions about services.

Therefore the Domain Name System is a communication network. And it will guide all of your visitors and direct them to the correct addresses or additional hostnames.

So after we made clear what DNS is, let’s examine few questions. They will help you determine if Premium DNS service is necessary for you or not.

  • What amount of people have to connect to your website?
  • How frequently will these people need to connect?
  • What is their location? Are most of them from your local country? Or maybe the visitors are from all around the world?
  • Does your site require some more extra security features? Is it that essential to have protection for your customers at every move they make through your site?

When is Premium DNS required?

Consider implementing Premium DNS service, for example, if your business generates a lot of traffic. In this way, you will be able to manage it and your worldwide presence. Uninterrupted uptime is crucial in this scenario. You have to be prepared to answer the millions of queries coming from all around the world.

Maybe you have to respond to the expectations for a high-security website. And ensure that transactions and users’ data are safe.   

Such examples are businesses like e-Commerce, banking, accounting systems, fintech companies, payments, government, and many more.


Any managed DNS service is a perfect solution if you own a small static site, a portfolio site, or maybe a blog. If the amount of visitors is not so significant, it is a good idea to use a free DNS service.   

If your site is not so small and you need additional features to provide better security or expand your business worldwide, it is better to choose to use Premium DNS service. It will provide a better performance, redundancy, security, and of course, speed.
