Er, oops:

        7 => b'7',
        8 => b'8',
        10 => b'A',
        11 => b'B',

That said, looks like the function generating the domain name for the IPv6 reverse lookup is broken in more ways.

I were not able to find, why it should not work with IPv6 address. But I am a newbie in Rust, so it does not mean much. But I thought IPv6 is supposed to be working from the code.
