2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns1.sj1.northsky.com, ns2.sj1.northsky.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 0 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS13446 (AS-NETZERO - Netzero,INC., US): 2 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
!

No IPv6

None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

✓ All respond #14

All 2 nameserver addresses answered.
✓ 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: ns1.sj1.northsky.com (64.136.25.253): dial tcp 64.136.25.253:53: connect: connection refused; ns2.sj1.northsky.com (64.136.44.123): dial tcp 64.136.44.123:53: connect: connection refused.

No EDNS

These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: ns1.sj1.northsky.com (64.136.25.253), ns2.sj1.northsky.com (64.136.44.123).

#20
✓ Public addresses #21

All nameserver addresses are publicly routable.

Unusual SOA timers

refresh 5m is outside 20m–1d; retry 5m should be shorter than refresh 5m. Current values: refresh 5m, retry 5m, expire 14d, negative TTL 5m.

Hidden master

The primary nameserver ns1.sj1.northsky.com.20m.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 dns@20m.com #25

The SOA RNAME dns.20m.com means dns@20m.com.
✓ Timestamp serial #26

The serial 1790907303 is a Unix timestamp (2026-10-02 02:15 UTC).

✓ TTLs within range #32

TTLs: A 5m, MX 5m, NS 5m. The NS TTL at the parent is 2d and in the zone 5m; resolvers may use either.
✓ No CNAME at the apex #33

The zone apex has no CNAME record.
i

Wildcard record

A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.

#34
i

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.
