Wrote a CLI tool to check DNS configurations quickly (an alternative to dig)
The heavylifting is done by this package: https://github.com/miekg/dns.

Why do clients ask the authoritive nameserver what is NS-records are?
Apart from `dig`, clients like https://github.com/miekg/dns show the same behavior.

Book recommendations for network programming
For the DNS i wrote a PiHole clone, which on the core it uses github.com/miekg/dns, to upstream queries and also to handle the custom entries, i've been wanting to publish that project but haven't done so cause the code is a bit messy since i did it as a PoC mostly, when comparing it to pihole it has the advantage that its really resource light mostly on the admin features, the dns resolving performs pretty much the same.

How to unit test net.Resolver?
You can do the same with net.Resolver, either by just setting it's Dial function (and PreferGo=true). You can use https://pkg.go.dev/golang.org/x/net/dns/dnsmessage or https://github.com/miekg/dns to implement an in-process server, either over TCP/UDP or skipping real networking completely, just like you can do with https://golang.org/pkg/net/http/httptest

Go 1.16 will make system calls through Libc on OpenBSD
Had a similar problem a couple years ago where I needed to use alternative DNS libraries to troubleshoot issues in a company's infrastructure.
Golang's rules for what implementation to use are found here: https://golang.org/pkg/net/#hdr-Name_Resolution
A really solid alternative DNS client implementation can be found here: https://github.com/miekg/dns. Real easy to read and vet compared to a few other libraries I ran into when working on this problem.
