DNS-NO-AAAA

No IPv6 address for the domain

What it means

IPv6-only networks (some mobile carriers and new ISPs) reach IPv4-only sites through translation, which usually works but adds latency and occasional breakage. Search engines and some scoring tools also note it.

How to fix it

  1. 1If your host supports IPv6, add an AAAA record for the apex and www.
  2. 2If it does not, this is a note, not a fault.

Re-check after the change

DNS changes can take up to the record's TTL to be seen; use Re-run on the result page to bypass our 10-minute cache.
