I just published a blog post about getaddrinfo and all the other weird DNS APIs that we use in Firefox to resolve HTTPS records.

All this was part of the talk I gave at FOSDEM last weekend.

getaddrinfo sucks. everything else is much worse

DNS is one of the critical building blocks of the internet and of the modern web. For the longest time the only way for Firefox to resolve a DNS domain was by using getaddrinfo.

I would just add that in #curl we use c-ares for the HTTPS RR stuff, on all the platforms.

@bagder we looked into c-ares as one alternative, but we'll probably go with a rust-based resolver like hickory-dns instead. It's not as mature but it raises fewer eyebrows when importing into Firefox 🙂
