Ummmm....

typedef uint32_t in_addr_t;
struct in_addr
{
in_addr_t s_addr;
};
So the "natural" representation of an IP address (on Linux, at least)
*is* an integer. Though that header file doesn't seem to indicate
whether this should be host-order or network-order. :-(
Does anyone know whether this is specified anywhere?
