Dig command – What is it, and what is it used for?
The Dig command is software with a command-line interface (CLI) that is designed for domain probing. The short abbreviation “Dig” stands for Domain Information Groper. It is a very helpful tool that can be used on devices with almost every operating system (OS), like macOS and Linux.
Through the Dig command, you have the ability to perform different types of DNS queries and receive valuable information about the DNS records, such as A, AAAA, MX, SOA, NS, or complete a Reverse DNS lookup and check PTR records.
You could utilize the command and inspect for difficulties that are related to your domain or the services you apply, such as email or FTP.
