I'm coming into this late, and perhaps under-armed ... but no, I don't understand. Network order == big-endian ... so on little-endian machines htons(), htonl() et. do actually perform a conversion. On a big-endian system, no conversion is necessary because network order == host order on these machines. This way, every host is transferring information in network order, so everyone's happy.
