  • ✓ 4 nameservers #6
    Delegated to a.ns.nyc.bitshelter.com, a.ns.sfo.bitshelter.com, b.ns.nyc.bitshelter.com, b.ns.sfo.bitshelter.com.
  • ✓ 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 2 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS3257 (GTT-BACKBONE - GTT Communications Inc., US): 1 address; AS40475 (APPLIEDOPS - Applied Operations, LLC, US): 1 address; AS62804 (BITSHELTER-NYC - PhotoShelter, Inc., US): 2 addresses.
  • 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
    DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: a.ns.nyc.bitshelter.com (69.22.188.122): dial tcp 69.22.188.122:53: connect: connection refused; a.ns.sfo.bitshelter.com (69.22.175.122): dial tcp 69.22.175.122:53: connect: connection refused; b.ns.nyc.bitshelter.com (69.22.188.123): dial tcp 69.22.188.123:53: connect: connection refused; b.ns.sfo.bitshelter.com (69.22.175.123): dial tcp 69.22.175.123:53: connect: connection refused.

Checks

  • ✓ TTLs within range #32
    TTLs: A 1h, MX 5m, NS 3d. The NS TTL at the parent is 2d and in the zone 3d; 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
  • ✓ CAA restricts issuance #35
    Certificates may be issued by: digicert.com, globalsign.com, godaddy.com, letsencrypt.org, sectigo.com, symantec.com, amazon.com.
