AAAA Record
An AAAA record is the DNS record that maps a hostname to an IPv6 address. This lookup lists the IPv6 addresses published for a name, with their TTLs.
When to use this: You are enabling IPv6 for a site or mail server, or IPv6-only visitors cannot reach you. Command prefix aaaa:
About the AAAA Record
Check the IPv6 (AAAA) addresses published for a hostname.
FAQ
- Do I need AAAA records?
- Not to work on IPv4, but clients on IPv6-only networks reach you faster with them, and mail servers increasingly connect over IPv6.
- Does IPv6 need reverse DNS too?
- For mail servers, yes: many receivers reject or penalize IPv6 senders without a matching PTR record.
