IPv6 breaks quietlyMonitor the AAAA record with Tenium so a bad IPv6 publish does not wait for a user report.
Start freeWhat an AAAA record is
AAAA is the IPv6 equivalent of an A record. Plenty of domains have working IPv4 and a broken or stale AAAA, and dual-stack clients can prefer the broken address.
No AAAA is normal
A domain with only A records is valid. An empty result here means “no IPv6 published”, not “the domain is down”.
