  .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 2027-09-08 #3

  The registration is valid until 2027-09-08 (320 days).
• ✓ Transfer locked #4

  Registry status: client delete prohibited, client transfer prohibited, client update 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: ns0100.secondary.cloudflare.com, ns0154.secondary.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 2 IPv4 /24s and 2 IPv6 /48s.
• i

  All nameservers in one AS

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

  Hidden master

  The primary nameserver ns2.seagate.com 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@seagate.com #25

  The SOA RNAME hostmaster.seagate.com means hostmaster@seagate.com.

Checks

• ✓ TTLs within range #32

  TTLs: A 5m, AAAA 5m, MX 1h, NS 4h. The NS TTL at the parent is 2d and in the zone 4h; 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.
