I would like to create a DNS resolver using Bind9 so all my organization's DNS queries go to this resolver (DNS queries for external domains. The resolver should not be authoritative for the organization's domain). I will restrict the incoming requests from the outside.

I tried to search for information about the the load that such resolver can handle:

  1. What is the rate of DNS queries that Bind9 can serve? How many queries per second? Probably, it is also a function of the machine and the bandwidth (assumed to be high), so response that is a function of the machine settings is good as well.
  2. Are there any other better alternatives?

Thanks!

F-Root is run by ISC and is running BIND 9. You can get the daily traffic stats. See https://root-servers.org/ to get the number of servers (currently 242). The recommended configuration is Dell PowerEdge R340 costing "about $3000 delivered." You should be able to math out the performance metrics you are looking for with this data.

(Yes, I'm joking.)
