I have ~700k (and growing) domain names that should be resolved daily. I'm trying to make it efficient as possible using the recursive BIND server (do you know a better option?), the goal is to get 2000 queries per second with minimum server\s cost.

I thought using a single packet for multiple queries might be more efficient than multiple UDPs. I'll try reading more about adns to reach more queries at the same TCP connection. Any better ideas?<br>

Do you know of a way to ask multiple DNS queries in a recursive bind server at the same packet\request? Using DoH might work? How? Is there a plugin which does that?</div>
