info

.fr country-code · IONOS SE · expires 2027-10-16

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 2027-10-16 #3

The registration is valid until 2027-10-16 (359 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.

2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: britney.nexylan.net, michael.nexylan.net.

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only in the zone: justin.nexylan.net. britney.nexylan.net, justin.nexylan.net, michael.nexylan.net report NS britney.nexylan.net justin.nexylan.net michael.nexylan.net.

#7
✓ 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 2 IPv4 /24s and 0 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS199758 (NEXYLAN - SAS Nexylan, 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 .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
!

No IPv6

None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: britney.nexylan.net: "PowerDNS Authoritative Server 5.0.7 (built Aug 6 2026 00:00:00 by mockbuild@localhost)"; justin.nexylan.net: "PowerDNS Authoritative Server 5.0.7 (built Aug 6 2026 00:00:00 by mockbuild@localhost)"; michael.nexylan.net: "PowerDNS Authoritative Server 5.0.7 (built Aug 6 2026 00:00:00 by mockbuild@localhost)". Hide or replace the version string.
