Did you happen to have a preference with regard to the specifier for
IPv6 addresses:

I was thinking of using %pI6 to replace NIP6() and NIP6_FMT and using
%#pI6 for NIP6_SEQFMT.

On the IPv4 side, maybe use %pI4 for network endian NIPQUAD() and NIPQUAD_FMT
and then %#pI4 for host-endian HIQUAD(), as displaying the IPv4 address without
the periods isn't useful?

What do you think of that?
