[Question] Disable recursive queries

[ammnt]

Hello,

it 's just a question. Some ISPs require that recursive queries be disabled due to high network load. How do I do this correctly on Debian 9 + AGH 0.99.2 to avoid losing AGH`s functionality?

Thank you.

AG is not a DNS recursor so this is not a problem, the recursive queries are performed on the DNS resolver side

I don 't understand. I receive notifications from my ISP to turn off recursive queries and proof-links:

Does anyone know how to turn them off on Debian 9 if you don 't have a full bind9? Unless most ISPs do so will disable services for violation Terms & Conditions. Please, explain.

Thank you.

Use firewall-iptables.

This makes little sense. It's more likely they just don't want you to run a public DNS server.
If so, I'd recommend changing the VPS provider.
