.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 2034-03-24 #3

The registration is valid until 2034-03-24 (2709 days).
i

No transfer lock

The domain has no transfer lock (status: active). A registrar lock protects against unauthorized transfers.

#4
✓ 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: redbusprimarydns.wn.com, redbussecondarydns.wn.com.

#6
✓ Parent and zone agree #7

The parent delegation and the zone's NS records list the same nameservers.
!

Glue differs from the zone

The addresses at the parent (glue) differ from the addresses in the zone: redbusprimarydns.wn.com (glue 195.149.84.231, zone 195.149.84.231, 2001:67c:38c::e7); redbussecondarydns.wn.com (glue 195.149.84.232, zone 195.149.84.232, 2001:67c:38c::e8). Update the glue at your registrar.

#8
✓ All names resolve #9

Every nameserver name has an address and is not an alias.
!

Nameservers in one network

all IPv4 addresses are in 195.149.84.0/24; all IPv6 addresses are in 2001:67c:38c::/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 (AS43081 (WORLD-NEWS - World News PTE. LTD, SG): 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.

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: redbusprimarydns.wn.com: "9.18.49-1~deb12u2-Debian"; redbussecondarydns.wn.com: "9.18.49-1~deb12u2-Debian". Hide or replace the version string.

✗

Zone transfer allowed

These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: redbusprimarydns.wn.com (195.149.84.231): 1806 records; redbusprimarydns.wn.com (2001:67c:38c::e7): 1806 records; redbussecondarydns.wn.com (195.149.84.232): 1806 records; redbussecondarydns.wn.com (2001:67c:38c::e8): 1806 records. Restrict zone transfers to your secondary servers.

#18
✓ 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.

Unusual SOA timers

refresh 2d is outside 20m–1d; negative caching TTL (minimum) 3m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 2d, retry 20m, expire 90d, negative TTL 3m.

Hidden master

The primary nameserver redbusprimarydns.worldnews.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.

✓ Contact root@wn.com #25

The SOA RNAME root.wn.com means root@wn.com.
✓ Timestamp serial #26

The serial 1761561973 is a Unix timestamp (2025-10-27 10:46 UTC).
