A library for network calculations would have to include IPv6, and 
ideally would interwork with (the equivalent of) DHCP etc. so that it 
could obtain things like router addresses.

The sort of operation that I've found irritating in the past- 
particularly when it had to be correct for both little- and big-endian 
architectures- was shifting a mask left or right as part of an attempt 
to determine whether a host was actually a router onto another subnet.
