Checks

  • ✓ 4 nameservers #6
    Delegated to ns1.siteground.com, ns2.siteground.com, ns3.siteground.com, ns4.siteground.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: ns1.siteground.com, ns2.siteground.com, ns3.siteground.com, ns4.siteground.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 4 IPv4 /24s and 0 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS15169 (GOOGLE - Google LLC, US): 4 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • 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.
    #13

    Unusual SOA timers
    refresh 1m is outside 20m–1d; retry 1m should be shorter than refresh 1m; expire 6m is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 1m, retry 1m, expire 6m, negative TTL 6m.
    #23
  • i
    Hidden master
    The primary nameserver ns-cloud-a1.googledomains.com is not listed as a nameserver: a hidden master that only feeds the public secondaries. That is a common setup; make sure it is not reachable for zone transfers from outside.

Checks

  • ✓ TTLs within range #32
    TTLs: A 6m, MX 6m, NS 6h. The NS TTL at the parent is 2d and in the zone 6h; 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.
  • 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.
