DNS AAAA Record

Sitecheck Team

Maps a hostname to an IPv6 address.

An AAAA record maps a hostname to an IPv6 address. It is the IPv6 equivalent of an A record.

Why it matters: IPv6 support improves reachability and future-proofs your infrastructure.

Quick tips:

  • Ensure your hosting provider supports IPv6 before adding AAAA records.
  • Keep A and AAAA records aligned for dual-stack support.
