    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: udns1.ultradns.net, udns2.ultradns.net.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: pdns1.ultradns.net, pdns2.ultradns.net, pdns3.ultradns.org, pdns4.ultradns.org, pdns5.ultradns.info, pdns6.ultradns.co.uk. pdns1.ultradns.net, pdns2.ultradns.net, pdns3.ultradns.org, pdns4.ultradns.org, pdns5.ultradns.info, pdns6.ultradns.co.uk, udns1.ultradns.net, udns2.ultradns.net report NS pdns1.ultradns.net pdns2.ultradns.net pdns3.ultradns.org pdns4.ultradns.org pdns5.ultradns.info pdns6.ultradns.co.uk udns1.ultradns.net udns2.ultradns.net.
    #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 8 IPv4 /24s and 6 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS12008 (VERCARA - Vercara, LLC, US): 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 .net
    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.
