Problems

  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ns3.coreroute.de (208.167.237.33): SERVFAIL, authoritative=false.
    #15
  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns3.coreroute.de (208.167.237.33): .
    #19
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    No EDNS
    Nameservers · These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: ns1.coreroute.de (104.156.136.44), ns2.coreroute.de (23.146.24.55), ns3.coreroute.de (208.167.237.33).
    #20
  • !
    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.
