See whether your AAAA record change has spread: 12 public resolvers, queried live, side by side.
Map key: each dot is the country where a resolver's operator is headquartered (number = resolvers), coloured by result. It does not show where the query ran — most of these resolvers are anycast networks with servers in many cities.
These are 12 large public resolvers, queried live over encrypted DNS-over-HTTPS from our servers. Most are anycast networks with many locations, so we show which resolver answered — not a city. Two (CIRA Canadian Shield) are run by the organization that operates .ca. Your ISP's resolver may still show an older answer until its cache expires.
An AAAA record maps a domain to an IPv6 address (like 2001:db8::1). It is the IPv6 twin of the A record. Browsers on IPv6-capable networks will prefer it, so a wrong AAAA can break a site for some visitors while it works for others.
Type your domain in the box above, keep AAAA selected and press Search. We ask 12 public DNS resolvers — including two run by CIRA Canadian Shield — at the same moment and show each answer side by side.
Each green row should list the same IPv6 address(es). A red row with "No AAAA record" is fine if you do not use IPv6. If you moved servers, make sure the AAAA record was updated or deleted — a stale one will send IPv6 visitors to the old host.
No. It is optional. If you publish one, the server must actually answer on that IPv6 address.
Usually a stale AAAA record: visitors on IPv6 go to the old server while IPv4 visitors reach the new one.
The same as any record: governed by the TTL of the old record.
