    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns1.stantec.com, ns2.stantec.com.
    #6
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • !
    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns2.stantec.com (glue 199.189.1.9, zone 159.21.0.9). 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 2 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS26574 (STANTEC - STANTEC CONSULTING SERVICES INC., CA): 1 address; AS62982 (STANTEC-US - STANTEC CONSULTING SERVICES INC., CA): 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 (0s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 2h; resolvers may use either.
