There's actually a comment near the definition of PortNumber http://hackage.haskell.org/packages/archive/network/latest/doc/html/src/Netw...
-- newtyped to prevent accidental use of sane-looking -- port numbers that haven't actually been converted to -- network-byte-order first. Why the hell isn't it exported to haddocks is beyond me.

This is a case where a line of documentation could save a lot of people a lot of trouble. Anyone have a clone of network handy that they could make a pull request from?

I might be mistaken, but is there a bug in the Show instance of PortNum?
Not a bug, an annoying misdesign (IMO). A PortNum is actually in network byte order. If you extract it, you get the original port; if you simply show it, you see it byteswapped on little-endian platforms.
