What
This is a package containing the bits of the old inet.af/netaddr package that didn't make it
into Go 1.18's net/netip standard library package.
As background, see:
- https://github.com/inetaf/netaddr/ (now deprecated)
- https://tailscale.com/blog/netaddr-new-ip-type-for-go/ - blog post about why the package came to be originally

This package requires Go 1.18+ to use and complements the net/netip.
FAQ
Why's it no longer under inet.af? Since that joke started, that
TLD is now under control of the Taliban. (Yes, we should've known
better. We'd even previously scolded people for relying on
questionable ccTLDs. Whoops.)
Will this stuff make it into the standard library? Maybe. We'll see.
