The most popular and most commonly used DNS record is exactly the A record. But, if you are just starting managing your network and you haven’t heard about it, don’t worry! Here is a little bit more information about it!
A record explained
The A record, also commonly known as address record, is a DNS (Domain Name System) resource record. It has the essential purpose of linking a domain name to its IP address (IPv4 address). Therefore every time a user desires to connect and explore a specific website, its browser is going to require the IP address which is provided with the A record. Thanks to it, it is going to understand exactly where that website is hosted and connect to it without any difficulties.
As we mentioned, the A record holds inside an IPv4 address, a 32-bit address that includes four combinations of digits divided by dots.
