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.

Conclusion.

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!

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.

  • 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.

Conclusion.

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.

What is DNS poisoning (DNS spoofing)?

Through a DNS poisoning attack, a hacker replaces the address of a legitimate website with a fake one. Once achieved, that hacker can steal delicate knowledge, like passwords and numbers of an account. The hacker can also deny loading your site, which is spoofed.

What does DNS poisoning mean?

DNS poisoning, also called DNS spoofing, is a technique, which hackers use. It manipulates identified weak spots inside the domain name system (DNS). 

When it is made, a hacker can direct traffic from one genuine site to a fake version of it. And because of the way DNS works, the infection can spread further.

How is DNS spoofing performed?

When you want to visit a site, your server pulls up a response from the hacker. Thus, the forged data is stored. And this makes DNS cache poisoning accomplished. 

A hacker can achieve this by:

  • Binding the server. Hackers are capable of sending a lot of queries to a caching server. Afterward, they send thousands of fake responses. And at some point, they take control of the root domain and the whole site.
  • Server simulation. The hacker responds a lot quicker with the wrong answer when your DNS server submits a query for a translation. And this is happening long before the correct server can do so.
  • Exploiting open ports. Hackers can send to DNS resolver ports thousands of queries. They identify which port is open in time. The focus for future attacks will be only on this port. 

DNS poisoning attacks are happening because the system is not secure enough. Your devices are holding conversations with servers with the help of the user datagram protocol (UDP). The connection is provided fast and efficiently. The problem is that no security measures are built-in. Your device is not able to verify the server’s identity. And also, it doesn’t validate the information that comes back.

It is easy to perform fabrication in such an environment. Someone can own the server you are corresponding with. And the fact that proving your identity is not a must. That could lead you to receive forged data and probably never know about it.

DNS poisoning and DNSSEC

DNS does not contain encryption. That makes intercepting the traffic with spoofing an easy job. Furthermore, DNS servers do not verify the IP addresses to which they are redirecting the traffic. 

Here comes DNSSEC, which is a protocol created to add more ways and methods of verification and make your DNS more secure. This protocol is able to generate an individual cryptographic signature and store it together with your other DNS records, like A record, CNAME, etc. Then your DNS resolver uses this specific signature to validate a DNS response. So this way, it is guaranteeing that the record wasn’t falsified.

DNSSEC is a great service that can help you protect yourself from DNS poisoning.

Conclusion.

DNS poisoning is a serious problem, and it could be terrifying. Protecting and configuring a DNS server accurately is going to help you to avoid such things from happening.
