I need my DNS server to resolve for my authoritative domain, I have 30+ domains
here I can't block acces to port 53.

Ah, it's a shared auth/recursive. In which case that's probably the best
you can do. Just be aware these IPs are probably spoofed - they are the
victims - so you should have some process to expire them over time.
FWIW this is one reason not to mix auth/recursive on the same server; it
tempts you to use the same IP.
