IPv6 Address Record
AAAA ("quad-A") is the IPv6 equivalent of A. Maps a domain to a 128-bit IPv6 address.
Syntax
domain_name TTL IN AAAA IPv6_address
Example
example.com. 300 IN AAAA 2606:2800:220:1:248:1893:25c8:1946
When to use
When: the host has an IPv6 address and you want to be reachable on IPv6-only networks.
Common mistakes
Common mistakes: A exists but AAAA missing — slower for IPv6-first clients. Or AAAA points to an IPv4-only host.
