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 · negative caching TTL (minimum) 2m30s is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 8h, retry 2h, expire 7d, negative TTL 2m30s.
    #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.
