  • ✓ 5 nameservers #6
    Delegated to dns01.sahibinden.com, dns02.sahibinden.com, dns03.sahibinden.com, dns04.sahibinden.com, dns05.sahibinden.com.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: dns01.sahibinden.com, dns02.sahibinden.com, dns03.sahibinden.com, dns04.sahibinden.com, dns05.sahibinden.com.
  • ✓ 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: AS34984 (TELLCOM-AS - Superonline Iletisim Hizmetleri A.S., TR): 4 addresses; AS396982 (GOOGLE-CLOUD-PLATFORM - Google LLC, US): 1 address.
  • i
    All nameserver names under .com
    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.

    No DNS over TCP

Checks

  • ✓ TTLs within range #32
    TTLs: A 5m, MX 1h, NS 5m. The NS TTL at the parent is 2d and in the zone 5m; 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.
