Instead of having three different address classes, allow the division between suffix and prefix to occur on an arbitrary boundary. The classless addressing scheme answers the problem by allowing an ISP to give a prefix. Prefix is 28 bits long.
This code properly implements the IP checksum function on a 32-bit machine: unsigned short cksum(unsigned short *buf, int count) { unsigned long sum = 0; while (count--) { sum += *
