IETF 101 DNS Hackathon Results

The IETF 101 hackathon has come and gone. I wanted to write up the results of this. See my original plan for the hackathon.

Implement DOH (DNS over HTTPs). Go DNS already implements DNS over TLS, so this shouldn’t be too hard

This turned out to be “too hard” (who would have guessed?). Basically DNS over HTTPS (DoH) doesn’t map to proper DNS at all. See my write up to the DoH mailing list.

The IETF 101 meeting is in London, and while I’m not going to the entire meeting, I thought it would be nice to go to the hackathon and work on Go DNS a bit.

This hackathon takes place in the weekend (and is free of charge, you’ll only need to register), so this leaves two days of ~~hacking~~^W careful coding.

I’m planning to work on the following bits:

Implement DOH (DNS over HTTPs). Go DNS already implements DNS over TLS, so this shouldn’t be too hard (famous last words). The plan here would be:

Extend the Net value in both Client and Server to include https variant.
Testing the client against one of the existing server implementations.
Getting Server side support going.
Unit tests

Time permitting implement gRPC in Go DNS in a “plug in my own transport” fashion. We use gRPC in CoreDNS and having it move to Go DNS would make life simpler. Of course DNS over gRPC is not a standard, so this needs to be pluggeable (there is not exact plan for this).
As these things all use TCP, it might also be worth looking a connection pooling. This is implemented in a CoreDNS plugin, called forward.
- Check if it makes sense to do in the Go DNS library.
- Make a plan.
- Implement.
- Profit.
