i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS42473 (AS-ANEXIA - Anexia Cloud Solutions GmbH, AT): 10 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

#11
✓ Nameserver names under 5 TLDs #12

Nameserver names use the TLDs .at, .cc, .com, .de, .systems.
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.
