[QUOTE="Victor Bazarov, post: 1542785"] This is a C++ newsgroup, and TCP/IP is off-topic. However, if you have 2 strings, where one is an encoded number and the other is an encoded mask, you need to (a) convert the number into an unsigned long (b) convert the mask into an unsigned long (c) perform bitwise AND on them (d) convert the result back into a string Use 'sscanf' to convert numbers from a string, and 'sprintf' to convert back.
