  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • !
    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns1.int-evry.fr (glue 157.159.11.52, 2001:660:3203:110:1::1, zone 157.159.11.52, 2001:660:3203:110::53:52). Update the glue at your registrar.
    #8
  • ✓ 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 3 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS1712 (FR-RENATER-ENST - Renater, FR): 4 addresses; AS2094 (FR-TELECOM-MANAGEMENT-SUDPARIS - Renater, EU): 3 addresses; AS2200 (FR-RENATER - Renater, FR): 5 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.

  • ✗
    Nameservers not responding
    These addresses did not answer, so resolvers waste time on timeouts: dns.univ-orleans.fr (2001:660:6402:1200::130): read udp [2a01:4f8:1c1c:eebf::1]:37772->[2001:660:6402:1200::130]:53: i/o timeout.
    #14
  • ✓ All authoritative #15
    Every responding nameserver answers authoritatively for the zone.
  • ✗
    Open recursion
    These nameservers resolve names for anyone, which makes them usable for DNS amplification attacks and cache poisoning: ns1.int-evry.fr (157.159.11.52), ns4.int-evry.fr (157.159.11.14). Disable recursion on authoritative servers.
    #16
  • !
    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.int-evry.fr: "9.16.23-RH"; ns2.int-evry.fr: "9.18.33"; ns4.int-evry.fr: "9.16.23-RH". Hide or replace the version string.
    #17
  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✓ TCP supported #19
    All nameservers answer over TCP.
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).
  • ✓ Public addresses #21
    All nameserver addresses are publicly routable.

    Unusual SOA timers
    refresh 1m is outside 20m–1d; expire 2h is shorter than 7d; secondaries stop answering too soon when the primary is down; negative caching TTL (minimum) 30s is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 1m, retry 30s, expire 2h, negative TTL 30s.

  • i
    Hidden master
    The primary nameserver diamant.int-evry.fr 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.
