An AAAA record is the IPv6 equivalent of an A record. It allows visitors using IPv6 to connect directly to the correct server.
Which value should you enter?
| Record type | AAAA |
| Value | IPv6 address, for example 2001:db8::10 |
| TTL | Use the default value unless a provider specifies otherwise. |
What should you consider?
- Publish an AAAA record only if the server and firewall properly support IPv6.
- Test the website over IPv6 before using the record widely.
- Keep A and AAAA records alongside each other for dual-stack availability.
DNS changes take time
After saving, an old value may temporarily remain in cache. Therefore, check not only in your browser but also with an external DNS checker.
Frequently asked questions
When will a change to AAAA become visible?
This depends on the TTL and provider caches. The change is often visible within a few minutes, but old responses may be retained for longer.
Can I undo a DNS change?
Yes. Restore the previous value and save again. This correction may also temporarily be affected by DNS cache.
Do I need to change the TTL?
Usually not. For a planned migration, you can lower the TTL in advance so later changes are retrieved more quickly.
