2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns10.ns365.net, ns9.ns365.net.

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only in the zone: ns11.ns365.net, ns12.ns365.net. ns11.ns365.net, ns12.ns365.net report NS ns10.ns365.net ns11.ns365.net ns12.ns365.net ns9.ns365.net.

#7
✓ 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 one network

all IPv4 addresses are in 124.173.109.0/24. 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 (AS134764 (CT-FoShan-IDC - CHINANET Guangdong province network, CN): 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 .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

Nameservers not responding

These addresses did not answer, so resolvers waste time on timeouts: ns10.ns365.net (124.173.109.204): read udp 46.225.38.91:54580->124.173.109.204:53: 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.

Identifying string disclosed

These nameservers answer version queries with a string that is not a version number: ns11.ns365.net: "www.gzidc.com"; ns9.ns365.net: "www.gzidc.com".

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✓ 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.

serial 2022052316 · primary main.ns365.net

✓ Serial 2022052316 everywhere #22

All nameservers serve the same version of the zone.
✓ Timers within recommendations #23

SOA refresh 3h, retry 33m20s, expire 7d, negative TTL 12h.

Hidden master

The primary nameserver main.ns365.net 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 root@main.ns365.net #25

The SOA RNAME root.main.ns365.net means root@main.ns365.net.
✓ Date-based serial #26

The serial 2022052316 follows the YYYYMMDDnn convention (2022-05-23).

6 records at the apex

✓ TTLs within range #32

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

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.
