List of DNS records every beginner should know

In the case of the A record, it maps the domain name to an IPv4 address, a 32-bit address. This address type has been around for a long time, and one day it will be completely replaced by the newer AAAA record. The AAAA record maps a domain name to an IPv6 address, a 128-bit address. The newer format is superior, but still, both are in use, and you can see both A and AAAA records for the same domain name. These are the first DNS records that you should learn.
