Checks

  • ✓ 3 nameservers #6
    Delegated to ns0.phase8.net, ns1.phase8.net, ns2.phase8.net.
  • ✓ 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.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS29550 (SIMPLYTRANSIT - Team Blue Carrier Limited, GB): 1 address; AS39729 (REGISTER-AS - REGISTER S.P.A., IT): 1 address; AS8622 (ISIONUK - TEAM BLUE INTERNET SERVICES UK LIMITED, GB): 1 address.
  • i
    All nameserver names under .net
    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.

Checks

  • ✓ TTLs within range #32
    TTLs: A 1h, MX 1h, 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.
  • i
    Wildcard record
    A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.
    #34
  • i
    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.
