Checks

  • i
    .fr is a country-code TLD (ccTLD)
    Country-code TLD: governed by its local registry under national policy, not by an ICANN contract. Registrar accreditation, dispute resolution and RDAP/WHOIS rules are set by the registry.
    #1
  • ✓ TLD delegated and signed #2
    .fr is delegated in the root zone and DNSSEC-signed.
  • ✓ Expires on 2027-10-19 #3
    The registration is valid until 2027-10-19 (362 days).
  • i
    No transfer lock
    The domain has no transfer lock (status: active, auto renew period). A registrar lock protects against unauthorized transfers.
    #4
  • ✓ Registry and delegation match #5
    The nameservers registered at the registry are the ones published in DNS.

Checks

  • ✓ 4 nameservers #6
    Delegated to ns-a.ecritel.com, ns-a.ecritel.fr, ns-b.ecritel.com, ns-b.ecritel.fr.
  • ✓ 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 4 IPv4 /24s and 0 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS8304 (ECRITEL-FRANCE - Ecritel SASU, FR): 4 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • ✓ Nameserver names under 2 TLDs #12
    Nameserver names use the TLDs .com, .fr.
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

    NSEC3 with extra iterations or salt
    NSEC3 uses 99 iterations and a 4-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.
