Checks

  • i
    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns1.above.com, ns2.above.com.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.above.com, ns2.above.com; only in the zone: ns1.abovedomains.com, ns2.abovedomains.com. ns1.above.com, ns1.abovedomains.com, ns2.above.com, ns2.abovedomains.com report NS ns1.abovedomains.com ns2.abovedomains.com.

  • !
    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns1.above.com (glue 103.224.182.77, 103.224.182.9, 103.224.212.9, zone 103.224.212.9, 103.224.182.85, 103.224.182.9, 103.224.182.77); ns2.above.com (glue 103.224.182.10, 103.224.212.10, 103.224.212.51, zone 103.224.212.51, 103.224.212.53, 103.224.212.10, 103.224.182.10). Update the glue at your registrar.
    #8
  • ✓ 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 0 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS133618 (TRELLIAN-AS-AP - Trellian Pty. Limited, AU): 16 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • 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
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13

    A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.

    Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
