Checks

  • i
    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: chance.ns.cloudflare.com, jacqueline.ns.cloudflare.com.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: chance.ns.cloudflare.com, jacqueline.ns.cloudflare.com; only in the zone: ns1.zenfolio.com, ns2.zenfolio.com. chance.ns.cloudflare.com, jacqueline.ns.cloudflare.com, ns1.zenfolio.com, ns2.zenfolio.com report NS ns1.zenfolio.com ns2.zenfolio.com.
    #7
  • ✓ 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 8 IPv4 /24s and 5 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS13335 (CLOUDFLARENET - Cloudflare, Inc., US): 16 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.

Checks

  • ✓ TTLs within range #32
    TTLs: A 5m, 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.

    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.
