  • ✓ 3 nameservers #6
    Delegated to dntps.mairie-metz.fr, ns1.neocenter-est.com, ns2.neocenter-est.com.
  • ✓ Parent and zone agree #7

    All nameservers are outside the zone, so no glue records are needed.
  • ✓ All names resolve #9

  • i
    One address family in one network
    all IPv6 addresses are in 2a06:e7c0::/48, while the other address family is spread over several networks.
    #10
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS202236 (NEO-CENTER-EST - Neo Center Est SARL, FR): 5 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, .fr.
  • i
    Partly IPv6
    These nameservers have no IPv6 address: dntps.mairie-metz.fr.
