Checks

  • ✓ 4 nameservers #6
    Delegated to cnudns.cines.fr, lirmm.lirmm.fr, nbison.lirmm.fr, ns2.nic.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: lirmm.lirmm.fr, nbison.lirmm.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 3 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS2200 (FR-RENATER - Renater, FR): 4 addresses; AS2486 (NIC-FR-DNS-UNICAST-PARIS2 - AFNIC (Association Francaise pour le Nommage Internet en Cooperation), FR): 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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: lirmm.lirmm.fr, nbison.lirmm.fr.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (1m), MX (2m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 3d; resolvers may use either.
