    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns0.as9105.com, ns0.tiscali.co.uk.

  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.tiscali.co.uk. ns0.as9105.com, ns0.tiscali.co.uk, ns1.tiscali.co.uk report NS ns0.as9105.com ns0.tiscali.co.uk ns1.tiscali.co.uk.
    #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 3 IPv4 /24s and 0 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS13285 (OPALTELECOM-AS - TalkTalk Communications Limited, GB): 3 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • ✓ Nameserver names under 2 TLDs #12
    Nameserver names use the TLDs .com, .uk.
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
