AAAA record
Maps a hostname to an IPv6 address. Named for being four times the size of an A record.
What one looks like
example.com. 3600 IN AAAA 2606:2800:220:1:248:1893:25c8:1946
Things worth knowing
- Roughly half of mobile traffic in some countries now arrives over IPv6.
- A broken AAAA record is worse than none: clients try IPv6 first and stall before falling back.
- Only publish one when the server genuinely answers on that address.
