Delegated to ns1.sberbank.ru, ns4.sberbank.ru, tmp1.sberbank.ru, tmp2.sberbank.ru.
✓ 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 one network

all IPv4 addresses are in 84.252.149.0/24. 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 (AS35237 (Sberbank - Sberbank of Russia PJSC, RU): 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 .ru

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.

Lame delegation

These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ns1.sberbank.ru (84.252.149.157): NOERROR, authoritative=false; ns4.sberbank.ru (84.252.149.158): NOERROR, authoritative=false; tmp1.sberbank.ru (84.252.149.157): NOERROR, authoritative=false; tmp2.sberbank.ru (84.252.149.158): NOERROR, 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: ns1.sberbank.ru: "PowerDNS Recursor 4.8.9"; ns4.sberbank.ru: "PowerDNS Recursor 4.8.9"; tmp1.sberbank.ru: "PowerDNS Recursor 4.8.9"; tmp2.sberbank.ru: "PowerDNS Recursor 4.8.9". Hide or replace the version string.

#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.

No SOA record

✓ Serial 2025101021 everywhere #22

All nameservers serve the same version of the zone.
