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

    #1
  • ✓ TLD delegated and signed #2
    .fr is delegated in the root zone and DNSSEC-signed.
  • ✓ Expires on 2027-02-01 #3
    The registration is valid until 2027-02-01 (102 days).
  • i
    No transfer lock

Checks

  • ✓ 3 nameservers #6
    Delegated to ns-28-a.gandi.net, ns-40-c.gandi.net, ns-98-b.gandi.net.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ 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 3 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS209453 (GANDI-LIVEDNS - GANDI SAS, FR): 4 addresses; AS29169 (GANDI-AS - GANDI SAS, FR): 2 addresses.
  • i
    All nameserver names under .net
    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.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (18s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 3h; resolvers may use either.
