What is an AAAA record?
A DNS record that maps a hostname to an IPv6 address.
Updated: October 9, 2026
An AAAA record maps a DNS name to a 128-bit IPv6 address and publishes the destination used for IPv6 connectivity.
Reading the result
Enter the hostname, not an IPv6 address, in DNS Lookup. Select AAAA, complete verification, and search. Query A for the same name to compare its published IPv4 and IPv6 destinations.
More than one AAAA record may be returned. NetKarte displays each IPv6 value and its TTL.
Limitations
The absence of an AAAA record is not necessarily an error. IPv4-only services may publish only A records.
DNS existence is not IPv6 connectivity
The illustrative addresses 2001:db8::10 and 2001:db8::11 are separate destinations, shown as separate records with TTLs. IPv6 zero compression is normal notation, not a cut-off value.
Retrieving AAAA does not prove your device or connection can reach that IPv6 address: NetKarte performs the DNS query from its server. Compare A and AAAA, then investigate device, network, and server IPv6 settings for connection failures. AAAA alone guarantees neither better speed nor safety.
