Recommended3

  • No IPv6 (AAAA) record

    Fix

    If your host supports IPv6, add an AAAA record to reach IPv6-only networks.

  • DNSSEC not enabled

    DNSSEC protects visitors from forged DNS answers.

    Fix

    Enable DNSSEC at your DNS provider, then add the DS record at your registrar.

  • Resolvers return different IP addresses

    Either a DNS change is still propagating, or the domain uses geo/load-balanced DNS.

    Fix

    If you recently changed DNS, wait for the old TTL to expire. Otherwise this is usually expected for CDNs.
