The AAAA DNS record maps a domain name to an IPv6 IP address, just as A records do for IPv4 addresses.
What is a DNS AAAA record?
The AAAA record allows a domain or subdomain (hostname) to be mapped to an IP address (128-bit IPv6).
An IPv6 address is written in hexadecimal and consists of 8 blocks/expressions of 16 bits separated by colons ":", for instance: fedc:6482:cafe:ba05:a200:e8ff:fe65:df9a
Here is an example of an AAAA record:
domain.com. 86400 IN AAAA fedc:6482:cafe:ba05:a200:e8ff:fe65:df9a| domain.com | record type | value or IP address | TTL |
|---|---|---|---|
| @ | AAAA | fedc:6482:cafe:ba05:a200:e8ff:fe65:df9a | 86400 |
DNS AAAA records function exactly like A records, except they store a domain's IPv6 address instead of its IPv4 address.
