Problems

  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Unusual SOA timers
    SOA · refresh 168h0m2s is outside 20m–1d. Current values: refresh 168h0m2s, retry 24h0m9s, expire 1680h0m2s, negative TTL 5m2s.
    #23
  • !
    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (3m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1d and in the zone 15m; resolvers may use either.
