.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 2027-07-09 #3

The registration is valid until 2027-07-09 (260 days).
✓ Transfer locked #4

Registry status: client delete prohibited, client transfer prohibited, client update prohibited, server delete prohibited, server transfer prohibited, server update prohibited.

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

Delegation

ns0.bt.net, ns1.bt.net, ns2.bt.net

Parent zone: com
Delegation from: a.gtld-servers.net (192.5.6.30)

NS in the zone: ns0.bt.net, ns1.bt.net, ns2.bt.net

Checks

✓ 3 nameservers #6

Delegated to ns0.bt.net, ns1.bt.net, ns2.bt.net.
✓ 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 0 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS2856 (BT-UK-AS - British Telecommunications Limited, GB): 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.

#13
