 For wallets wanting to get a head start on implementing human-readable bitcoin names, here’s a library that handles all the DNS parts!

* resolves against a local (/remote) TCP/53 resolver
* resolves against a DoH/DoT resolver
* creates/validates proofs

https://docs.rs/dnssec-prover/

It can even be run in WASM on a web page (and resolve via DoH directly)!

 Why only tcp/53, not also udp/53?

 I mean it could work over that too but then you have to handle truncation and tcp fallback and that’s annoying

 UDP is kinda default for DNS mostly.

 Default yes but servers MUST support both, for fallback :). When talking to an authoritative server, UDP is important, but when talking to a recursive resolver, who cares?
