  • ✓ 3 nameservers #6
    Delegated to odns0.nifty.ad.jp, odns1.nifty.ad.jp, odns2.nifty.ad.jp.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ 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.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS16509 (AMAZON-02 - Amazon.com, Inc., US): 2 addresses; AS4713 (OCN - NTT DOCOMO BUSINESS,Inc., JP): 1 address.
  • i
    All nameserver names under .jp
    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
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
