IPv4 Address to Integer

Problem

Convert a dotted IPv4 address string to its 32-bit unsigned integer value.

Treat the four octets as base-256 digits: multiply the running value by 256 and add each octet in order. Assume the address is well formed.

Hint

192.168.1.1 is 192 * 256 cubed plus 168 * 256 squared and so on.
