Come to think of it, this probably applies to IPv6 as well. Moving to

Thanks, Stefan. Patch applied.

Hi,

I was a bit stumped recently to realize that both inet_ntop() and
inet_pton() work with addresses in network byte order. inet_ntop.3
mentions that, and the example from inet_pton(), as far as I can tell,
implies that you can call inet_ntop() on the result of inet_pton(), so
the byte order needs to match, but I think it's better to mention this
explicitly in the man page text. How about this (patch against git)?
