  • ✓ 4 nameservers #6
    Delegated to dns1.chru-strasbourg.fr, dns2.chru-strasbourg.fr, dns3.chru-strasbourg.fr, dns4.chru-strasbourg.fr.
  • ✓ 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: dns1.chru-strasbourg.fr, dns2.chru-strasbourg.fr, dns3.chru-strasbourg.fr, dns4.chru-strasbourg.fr.
  • ✓ 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.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS15557 (LDCOMNET - Societe Francaise Du Radiotelephone - SFR SA, FR): 2 addresses; AS2259 (FR-RAREST - Renater, EU): 2 addresses.
  • i
    All nameserver names under .fr
    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.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (30s), MX (30s), NS (30s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 30s; resolvers may use either.
    #32
  • ✓ No CNAME at the apex #33
    The zone apex has no CNAME record.
  • ✓ No wildcard #34
    Names that don't exist return NXDOMAIN.

    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.
