A and AAAA records are among the most important in the DNS system. The process of resolving a domain name to find the IP address is managed by these two types of DNS records. This is what makes them valuable and essential to access the internet easily and quickly.
What does A record mean?
A record is the most popular and simple type used in DNS servers, where “A” stands for Address. The A record uses a domain name to find the device’s IP address connected to the Internet.
Consider the following example – You are a web user and want to access www.abc123.com. This request is sent to the DNS resolver. It identifies the IP, and then the page automatically loads.
In other words, the A record uses the domain name to find the IP address (IPv4 address).
