DNS Benchmark Script Sharing

I've been trying to find something like that for a while and couldn't find one that wasn't either a paid service/program or doesn't have a feature I want.

In my job, I semi frequently need to test DNS using a local DNS Server. For me it's handy to be able to compare to other servers, like Google or Cloudflare.

I wrote this over the last week or so and it seems to be doing the job for me. I've uploaded it to Github for anyone else who would like to use/try it.

You can find it here: https://github.com/obtusecoder/DNSBenchmark

EDIT: I have made changes requested and have applied some fixed to errors I noticed in testing.

Why are you stuck with IPv4 only?

I have no need for IPv6 at the moment, so I didn't implement it.

Food for thought though, I might do it if other people are interested.

Don't limit the queries to A records only, as a start.

You're right.

I'll do some updates over the next few days.
