Registration

info

.fr country-code · GANDI · expires 2033-10-07

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 2033-10-07 #3

The registration is valid until 2033-10-07 (2542 days).
i

No transfer lock

The domain has no transfer lock (status: active). 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.

2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns-quad.ibisc.univ-evry.fr, ns.lacl.fr.

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only at the parent: ns-quad.ibisc.univ-evry.fr; only in the zone: lacl2.lacl.fr. ns.lacl.fr report NS lacl2.lacl.fr ns.lacl.fr.

#7
✓ Glue present and correct #8

Glue is published for the nameservers inside the zone: ns.lacl.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 0 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS2200 (FR-RENATER - Renater, FR): 3 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

#11
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.

#13

✗

Nameservers not responding

These addresses did not answer, so resolvers waste time on timeouts: lacl2.lacl.fr (193.48.143.254): read udp 46.225.38.91:46066->193.48.143.254:53: i/o timeout.

#14
✗

Lame delegation

These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ns-quad.ibisc.univ-evry.fr (195.221.162.126): REFUSED, authoritative=false.

#15
✓ No recursion #16

The nameservers do not answer recursive queries for other domains.
!

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns.lacl.fr: "9.20.29-1~deb13u1-Debian". Hide or replace the version string.

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✗

No DNS over TCP

DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns-quad.ibisc.univ-evry.fr (195.221.162.126): .

#19
✓ EDNS supported #20

All nameservers support EDNS(0).
✓ Public addresses #21

All nameserver addresses are publicly routable.

serial 2026070839 · primary dnsdhcp.lacl.fr

✓ Serial 2026070839 everywhere #22

All nameservers serve the same version of the zone.
✓ Timers within recommendations #23

SOA refresh 8h, retry 2h, expire 14d, negative TTL 1d.
i

Hidden master (not resolvable)

The primary nameserver dnsdhcp.lacl.fr is not listed as a nameserver and does not resolve publicly: a hidden master, or a placeholder name. Some tools (e.g. dynamic updates) use MNAME to find the primary.

#24
✓ Contact hostmaster@lacl.fr #25

The SOA RNAME hostmaster.lacl.fr means hostmaster@lacl.fr.
✓ Date-based serial #26

The serial 2026070839 follows the YYYYMMDDnn convention (2026-07-08).

No CAA records

Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
