    Delegated to ns.domainnetwork.se, ns2.domainnetwork.se, ns3.domainnetwork.com.
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns3.domainnetwork.com. ns.domainnetwork.se, ns2.domainnetwork.se, ns3.domainnetwork.com report NS ns.domainnetwork.se ns2.domainnetwork.se.
    #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 2 IPv4 /24s and 2 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS12008 (VERCARA - Vercara, LLC, US): 6 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, .se.
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
