The Domain Name System (DNS) matches the domain names to their corresponding IP addresses. Thus, DNS records give the information for your hostname, domain, and IP address. With DNS records, you can adjust your domain configuration. There are many types of DNS records, but let’s start with the top 4 most popular of them.
A record and AAAA record
The A record is probably the most popular DNS record because it is used in almost any DNS system. It is an address record, so its purpose is to point a domain name to the corresponding IP address. Thanks to that, humans are not required to remember long and difficult numbers (IP addresses). Yet, the A record is usable when we are talking about IPv4 addresses.
In case when we want to point a domain name to an IPv6 address, we have to use the AAAA record. It is not so commonly used in comparison to the A record. However, the amount of new devices is rapidly growing, so eventually,, the IPv6 and the AAAA record will also gain popularity.
