Checks

  • ✓ 3 nameservers #6
    Delegated to bxnms.u-bordeaux.fr, dns.sciencespobordeaux.fr, dns2nd.sciencespobordeaux.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.sciencespobordeaux.fr, dns2nd.sciencespobordeaux.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 1 IPv6 /48.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS2200 (FR-RENATER - Renater, FR): 1 address; AS2202 (FR-RENATER-REAUMUR - Renater, EU): 3 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: dns.sciencespobordeaux.fr, dns2nd.sciencespobordeaux.fr.
