2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns01.graficom.com, ns02.graficom.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.
✓ 2 autonomous systems #11

The nameservers are spread over: AS51088 (A2B - A2B IP B.V., NL): 1 address; AS57795 (NGNETWORKS - NG-BLU Networks B.V., NL): 1 address.
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.

!

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns02.graficom.com: "9.18.39-0ubuntu0.24.04.8-Ubuntu". Hide or replace the version string.

#17
✗

Zone transfer allowed

These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: ns02.graficom.com (64.26.34.42): 189 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.
