    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns1.lightningsource.com (glue 12.230.218.171, zone 4.37.103.9). 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 3 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS13702 (INGRAM-BOOK-GROUP - Ingram Book Group, US): 1 address; AS3356 (LEVEL3 - Level 3 Parent, LLC, US): 1 address; AS5413 (Wavenet-AS5413 - Wavenet Limited, GB): 1 address.
  • 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.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (30s), MX (30s). Low TTLs are useful just before a planned change.
