Checks

  • i
    .fr is a country-code TLD (ccTLD)

  • ✓ 3 nameservers #6
    Delegated to dns-ovh.ut-capitole.fr, dns-ut1.ut-capitole.fr, heimdall.ut-capitole.fr.
  • ✓ 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: dns-ovh.ut-capitole.fr (glue 51.255.46.178, zone 51.178.45.211). 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 2 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS16276 (OVH - OVH SAS, FR): 1 address; AS2200 (FR-RENATER - Renater, 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
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
