.fr country-code · NAMESHIELD · expires 2027-07-25

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 2027-07-25 #3

The registration is valid until 2027-07-25 (276 days).
✓ Transfer locked #4

Registry status: client transfer prohibited, client delete prohibited.
✓ 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: dns1.sdv.fr, dns2.sdv.fr.

#6
✓ 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 one network

all IPv4 addresses are in 212.95.66.0/24; all IPv6 addresses are in 2001:810::/48. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).

#10
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS8839 (SDV-AS - SDV6TM SAS, 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
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
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.

✓ All respond #14

All 4 nameserver addresses answered.
✓ All authoritative #15

Every responding nameserver answers authoritatively for the zone.
✓ No recursion #16

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

Identifying string disclosed

These nameservers answer version queries with a string that is not a version number: dns1.sdv.fr: "not currently available".

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✓ TCP supported #19

All nameservers answer over TCP.
✓ EDNS supported #20

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

All nameserver addresses are publicly routable.

serial 2025052395 · primary dns0.sdv.fr

✓ Serial 2025052395 everywhere #22

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

SOA refresh 3h, retry 1h, expire 14d, negative TTL 1d.
i

Hidden master

The primary nameserver dns0.sdv.fr is not listed as a nameserver: a hidden master that only feeds the public secondaries. That is a common setup; make sure it is not reachable for zone transfers from outside.

#24
✓ Contact hostmaster@sdv.fr #25

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

The serial 2025052395 follows the YYYYMMDDnn convention (2025-05-23).
