  • ✓ 4 nameservers #6
    Delegated to dns103.kddi.ne.jp, dns104.kddi.ne.jp, dnsa01.kddi.ne.jp, dnsa02.kddi.ne.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 2 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS16509 (AMAZON-02 - Amazon.com, Inc., US): 2 addresses; AS2516 (KDDI - KDDI CORPORATION, JP): 4 addresses.
  • 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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: dnsa01.kddi.ne.jp, dnsa02.kddi.ne.jp.

Checks

  • ✓ TTLs within range #32
    TTLs: A 1d, AAAA 1d, MX 5m, NS 1d. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.
  • ✓ No CNAME at the apex #33
    The zone apex has no CNAME record.
  • ✓ No wildcard #34
    Names that don't exist return NXDOMAIN.

    No CAA records
    Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
