Checks

  • ✓ 4 nameservers #6
    Delegated to ns1.enterprise.com, ns2.enterprise.com, ns3.enterprise.com, ns4.enterprise.com.
  • ✓ 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.
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 2 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS13893 (EHI-NA-AS-1 - Enterprise Holdings, Inc., US): 4 addresses; AS16711 (EHI-NA-AS-2 - Enterprise Holdings, Inc., US): 4 addresses.
  • i
    All nameserver names under .com
    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.

  • ✗
    Nameservers not responding
    These addresses did not answer, so resolvers waste time on timeouts: ns3.enterprise.com (2620:103:e002:22b::18): read udp [2a01:4f8:1c1c:eebf::1]:59942->[2620:103:e002:22b::18]:53: i/o timeout.
    #14
  • ✓ All authoritative #15
    Every responding nameserver answers authoritatively for the zone.
  • ✓ No recursion #16
    The nameservers do not answer recursive queries for other domains.
  • ✓ No version disclosed #17
    The nameservers don't reveal their software version.
  • ✓ 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: ns2.enterprise.com (2620:103:e009:22b::17): dial tcp [2620:103:e009:22b::17]:53: i/o timeout; ns4.enterprise.com (2620:103:e009:22b::18): dial tcp [2620:103:e009:22b::18]:53: i/o timeout.
    #19
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).
  • ✓ Public addresses #21

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (30s), AAAA (30s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1d; resolvers may use either.

    No CAA records
    Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
