Checks

  • ✓ 4 nameservers #6
    Delegated to ccpntc3.in2p3.fr, ccpnvx.in2p3.fr, dns.univ-lyon1.fr, dns2.univ-lyon1.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: dns.univ-lyon1.fr, dns2.univ-lyon1.fr.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • i
    One address family in one network
    all IPv6 addresses are in 2001:660:5001::/48, while the other address family is spread over several networks.
    #10
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS2060 (FR-RENATER - Renater, EU): 2 addresses; AS2200 (FR-RENATER - Renater, FR): 2 addresses; AS789 (IN2P3 - 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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: ccpntc3.in2p3.fr, ccpnvx.in2p3.fr.

    Serials differ

This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.
