This module is responsible for defining the following basic networking types:
It declares ntoh[sl]() and hton[sl]().
It declares inet_aton(), inet_ntop(), and inet_pton().
It ensures that INADDR_LOOPBACK, INADDR_ANY, IN6ADDR_ANY_INIT, in6addr_any, and in6addr_loopback are available.
It ensures that IN_MULTICAST() is available to check for multicast addresses.
