  .com is a generic TLD (gTLD)

  Generic TLD under an ICANN registry agreement: ICANN-accredited registrars, UDRP and RDAP apply.

  #1
• ✓ TLD delegated and signed #2

  .com is delegated in the root zone and DNSSEC-signed.
• ✓ Expires on 2027-11-18 #3

  The registration is valid until 2027-11-18 (392 days).
• ✓ Transfer locked #4

  Registry status: client transfer prohibited.
• ✓ Registry and delegation match #5

  The nameservers registered at the registry are the ones published in DNS.

• ✓ 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 6 IPv4 /24s and 6 IPv6 /48s.
• i

  All nameservers in one AS

  All nameserver addresses are announced by one network operator (AS21342 (AKAMAI-ASN2 - Akamai International B.V., NL): 12 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
• ✓ All reachable over IPv6 #13

  Every nameserver has an IPv6 address.

Serial per nameserver

Checks

• ✓ Serial 2950634507 everywhere #22

  All nameservers serve the same version of the zone.

  SOA refresh 1h, retry 30m, expire 28d, negative TTL 1d.
• i

  Hidden master

  The primary nameserver ns1.benchmark.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 root@benchmark.fr #25

  The SOA RNAME root.benchmark.fr means root@benchmark.fr.
• ✓ Timestamp serial #26

  The serial 2950634507 is a Unix timestamp (2063-07-02 20:41 UTC).

193.108.91.165:53

Checks

• ✓ TTLs within range #32

  TTLs: A 8h, MX 8h, NS 8h. The NS TTL at the parent is 2d and in the zone 8h; resolvers may use either.
• ✓ No CNAME at the apex #33

  The zone apex has no CNAME record.
• i

  Wildcard record

  A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.
