One address family in one network

all IPv6 addresses are in 2001:6a8:3c80::/48, while the other address family is spread over several networks.

i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS2611 (BELNET - BELNET, BE): 5 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 .be

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.

i

Partly IPv6

These nameservers have no IPv6 address: dnsext.irceline.be.

Lame delegation

These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ns2.belnet.be (193.190.182.40): SERVFAIL, authoritative=false; ns2.belnet.be (2001:6a8:3c80:c000::40): SERVFAIL, authoritative=false.

#15
✓ No recursion #16

The nameservers do not answer recursive queries for other domains.
!

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dnsext.irceline.be: "9.11.4-P2-RedHat-9.11.4-26.P2.el7_9.14". 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: dnsext.irceline.be (193.190.137.132): 163 records. Restrict zone transfers to your secondary servers.

#18
✗

No DNS over TCP

DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns2.belnet.be (193.190.182.40): ; ns2.belnet.be (2001:6a8:3c80:c000::40): .

#19
✓ EDNS supported #20

All nameservers support EDNS(0).
✓ Public addresses #21

All nameserver addresses are publicly routable.
