  • i
    .com is a generic TLD (gTLD)
    Generic TLD under an ICANN registry agreement: ICANN-accredited registrars, UDRP and RDAP apply.
    #1
  • ✓ TLD delegated and signed #2
    .com is delegated in the root zone and DNSSEC-signed.
  • ✓ Expires on 2026-12-06 #3
    The registration is valid until 2026-12-06 (44 days).
  • i
    No transfer lock
    The domain has no transfer lock (status: active). A registrar lock protects against unauthorized transfers.
    #4
  • ✓ Registry and delegation match #5
    The nameservers registered at the registry are the ones published in DNS.

Checks

  • i
    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns3.myhostadmin.net, ns4.myhostadmin.net.
    #6
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • i
    One address family in one network
    all IPv6 addresses are in 240e:d9:c200::/48, while the other address family is spread over several networks.
    #10
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS38283 (CHINANET-SCIDC-AS-AP - CHINANET SiChuan Telecom Internet Data Center, CN): 5 addresses; AS4811 (CHINANET-SHANGHAI-MAN - China Telecom (Group), CN): 1 address.
  • i
    All nameserver names under .net
    All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.
    #12
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.

  • ✓ All respond #14
    All 6 nameserver addresses answered.
  • ✓ All authoritative #15
    Every responding nameserver answers authoritatively for the zone.
  • ✓ No recursion #16
    The nameservers do not answer recursive queries for other domains.
  • !
    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns3.myhostadmin.net: "v1.1"; ns4.myhostadmin.net: "v1.1". Hide or replace the version string.
    #17
  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✗
    No DNS over TCP
    DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns3.myhostadmin.net (118.123.249.114): dial tcp 118.123.249.114:53: i/o timeout; ns3.myhostadmin.net (61.172.183.77): dial tcp 61.172.183.77:53: i/o timeout; ns3.myhostadmin.net (240e:d9:c200::2): dial tcp [240e:d9:c200::2]:53: i/o timeout; ns4.myhostadmin.net (211.149.230.100): dial tcp 211.149.230.100:53: i/o timeout; ns4.myhostadmin.net (240e:d9:c200:1::2): dial tcp [240e:d9:c200:1::2]:53: i/o timeout.
    #19
  • !
    No EDNS
    These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: ns3.myhostadmin.net (61.172.183.77).
    #20
  • ✓ Public addresses #21
    All nameserver addresses are publicly routable.

    CNAME at the apex
    The zone apex is a CNAME to xmqsmjjjwx.gotoip3.com. A CNAME can't coexist with the SOA and NS records (RFC 1034); use your provider's ALIAS/flattening feature instead.
