2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns.dns.net.cn, ns7.dns.net.cn.

#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 0 IPv6 /48s.
✓ 2 autonomous systems #11

The nameservers are spread over: AS4808 (CHINA169-BJ - China Unicom Beijing Province Network, CN): 1 address; AS4847 (CNIX-AP - China Networks Inter-Exchange, CN): 1 address.

All nameserver names under .cn

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

fail

1 of 2 addresses answer authoritatively

Nameserver	Answer	Recursion	TCP / EDNS	AXFR	Version
ns.dns.net.cn 61.135.129.2	no response	no	no / no	-	-

✗

Nameservers not responding

These addresses did not answer, so resolvers waste time on timeouts: ns.dns.net.cn (61.135.129.2): read udp 46.225.38.91:48527->61.135.129.2:53: i/o timeout.

#14
✓ All authoritative #15

Every responding nameserver answers authoritatively for the zone.
✓ No recursion #16

The nameservers do not answer recursive queries for other domains.
✓ No version disclosed #17

The nameservers don't reveal their software version.
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✗

No DNS over TCP

DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns7.dns.net.cn (118.145.6.5): dial tcp 118.145.6.5:53: i/o timeout.

#19
!

No EDNS

These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: ns7.dns.net.cn (118.145.6.5).

#20
✓ Public addresses #21

All nameserver addresses are publicly routable.

warn

serial 166 · primary ns7.dns.net.cn

✓ Serial 166 everywhere #22

All nameservers serve the same version of the zone.
!

Unusual SOA timers

refresh 15m is outside 20m–1d; expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 15m, retry 10m, expire 1d, negative TTL 1h.

#23
✓ Primary is a public nameserver #24

The primary nameserver ns7.dns.net.cn is one of the listed nameservers.
✓ Contact admin@dns.net.cn #25

The SOA RNAME admin.dns.net.cn means admin@dns.net.cn.
✓ Counter serial #26

The serial 166 is a plain counter.
