  • 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 2031-06-19 #3
    The registration is valid until 2031-06-19 (1700 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: ns4.myhostadmin.net, ns5.myhostadmin.net.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.myhostadmin.net, ns2.myhostadmin.net, ns3.myhostadmin.net, ns6.myhostadmin.net. ns1.myhostadmin.net, ns2.myhostadmin.net, ns3.myhostadmin.net, ns4.myhostadmin.net, ns5.myhostadmin.net, ns6.myhostadmin.net report NS ns1.myhostadmin.net ns2.myhostadmin.net ns3.myhostadmin.net ns4.myhostadmin.net ns5.myhostadmin.net ns6.myhostadmin.net.
    #7
  • ✓ 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): 16 addresses; AS4811 (CHINANET-SHANGHAI-MAN - China Telecom (Group), CN): 3 addresses.
  • 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.
