  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.selectel.org, ns2.selectel.org, ns3.selectel.org, ns4.selectel.org; only in the zone: ns1.selectel.ru, ns2.selectel.ru, ns3.selectel.ru, ns4.selectel.ru. ns1.selectel.org, ns1.selectel.ru, ns2.selectel.org, ns2.selectel.ru, ns3.selectel.org, ns3.selectel.ru, ns4.selectel.org, ns4.selectel.ru report NS ns1.selectel.ru ns2.selectel.ru ns3.selectel.ru ns4.selectel.ru.
    #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 2 IPv4 /24s and 4 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS49505 (SELECTEL - JSC Selectel, RU): 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 .org
    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.

  • ✓ TTLs within range #32
    TTLs: A 1h, MX 1h, NS 59m56s. The NS TTL at the parent is 2d and in the zone 59m56s; 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.
