2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns8.san.yahoo.com, ns9.san.yahoo.com.

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only at the parent: ns8.san.yahoo.com, ns9.san.yahoo.com; only in the zone: ns1.turbify.com, ns2.turbify.com. ns1.turbify.com, ns2.turbify.com, ns8.san.yahoo.com, ns9.san.yahoo.com report NS ns1.turbify.com ns2.turbify.com.

#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 different networks #10

The nameservers are spread over 6 IPv4 /24s and 0 IPv6 /48s.
✓ 3 autonomous systems #11

The nameservers are spread over: AS14618 (AMAZON-AES - Amazon.com, Inc., US): 2 addresses; AS16509 (AMAZON-02 - Amazon.com, Inc., US): 2 addresses; AS8075 (MICROSOFT-CORP-MSN-AS-BLOCK - Microsoft Corporation, US): 2 addresses.
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: ns8.san.yahoo.com: "PowerDNS Authoritative Server 5.1.4 (built Aug 10 2026 13:38:30 by root@bh-centos-8.dev.cpanel.net)"; ns9.san.yahoo.com: "PowerDNS Authoritative Server 5.1.4 (built Aug 10 2026 13:38:30 by root@bh-centos-8.dev.cpanel.net)". 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.

This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.
