    NS sets differ
    The nameservers at the parent and in the zone should be the same.

    #7
  • ✓ 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 4 IPv4 /24s and 4 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS1921 (RCODEZERO-ANYCAST-SEC1-TLD - ipcom GmbH, AT): 6 addresses; AS394354 (CIRA-CLOUD2 - CIRA Canadian Internet Registration Authority Autorit Canadienne pour les enregistrements Internet, CA): 4 addresses; AS55195 (CIRA-CLOUD1 - CIRA Canadian Internet Registration Authority Autorit Canadienne pour les enregistrements Internet, CA): 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.
