    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns2.reedelsevier.com (glue 198.176.82.98, zone 198.176.82.118); ns3.reedelsevier.com (glue 198.176.82.101, zone 198.176.84.118). 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: AS133782 (ELSEVIER-ASIAPACIFIC-AS-AP - Elsevier Ltd, JP): 1 address; AS32472 (LEXIS2-AS - RELX inc., US): 1 address; AS59724 (REED-ELSEVIER-EMEA-GCC - Elsevier 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 (59s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1h; resolvers may use either.
