  .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 2026-12-02 #3

  The registration is valid until 2026-12-02 (41 days).
• ✓ Transfer locked #4

  Registry status: client delete prohibited, client transfer 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: agustin.ns.cloudflare.com, monika.ns.cloudflare.com.

  #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 different networks #10

  The nameservers are spread over 6 IPv4 /24s and 4 IPv6 /48s.
• i

  All nameservers in one AS

  All nameserver addresses are announced by one network operator (AS13335 (CLOUDFLARENET - Cloudflare, Inc., US): 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 .com

  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.

DS at the parent

DNSKEY in the zone

Checks

• ✓ Signed and validated #27

  The zone is signed, the parent publishes a DS record, and the resolver validates the answers.
• ✓ DS matches a key #28

  The DS record at the parent matches a key in the zone: key tag 2371 (SHA256).
• ✓ Modern algorithms #29

  Key algorithms: ECDSAP256SHA256 (13).
• ✓ Short-lived signatures (online signing) #30

  Signatures are valid for 50h0m0s and created on demand; the current one was made at 2026-10-21 08:21 UTC and expires at 2026-10-23 10:21 UTC.
• i

  NSEC

  The zone uses NSEC, so its full contents can be listed by walking the NSEC chain. That is fine unless the names are sensitive.

108.162.195.90:53

Checks

• ✓ TTLs within range #32

  TTLs: A 5m, AAAA 5m, MX 5m, NS 1d. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.
• ✓ No CNAME at the apex #33

  The zone apex has no CNAME record.
• ✓ No wildcard #34

  Names that don't exist return NXDOMAIN.
• i

  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.
