miekg/dns is really excellent. Our custom DNS server is written in Rust (with the NLNet libraries, which are also great), but I used miekg/dns to throw together a DNS telemetry system that we use to keep metrics on our DNS (and UDP) service from around the world using off-net hosts, which sounds cool to type out but was an absurdly simple coding project because of how good the libraries are.

More people should do cool weird stuff with DNS. (And Replit should host stuff on Fly! But also the DNS stuff we're talking about.)

It's a great post, thanks for writing it.
