My DNS server is receiving hundreds of query request in every minutes from unknown users.

How can I stop this?

Step 1: Don't run a public DNS server. Use a hosted solution. I've just been over the reasons why with another user. There's no decent reason for running your own IMO, at least not for external production hosting.

There doesn't need to be a step 2 but if you're really determined, your DNS server might be being used to contribute to a DDoS attack on another host. DNS servers will recurse to answer a query and this can cause allow massive traffic swarms from DNS servers. I'm saying you could inadvertantly be part of that swarm.

Fixing it is simple enough: don't run a DNS server or disable external recursion.
