Currently I have the following code to validate the first format. Also, please suggest a mechanism tovalidate the second format(address:port) also.[code snipped] if ((b1 | b2 | b3 | b4) Yes, 'unsigned' a short name for 'unsigned int', like 'long' is a shortname for 'long int' etc.So, back to the drawing board: rc = sscanf(ipadd, "%3u.%3u.%3u.%3u%c%u%c", &b1, &b2, &b3, &b4, &sep, &port, &c); if (rc ! So, back to the drawing board: rc = sscanf(ipadd, "%3u.%3u.%3u.%3u%c%u%c", &b1, &b2, &b3, &b4, &sep, &port, &c); if (rc ! You could also argue that because of locale's the above will catch...0.0.0.0:1,000 ...it won't if the thousands seperator is '.' (which it is in germany for instance) ... The truley strict versions I've seen/written don't use scanf().Currently I have the following code to validate the first format. Also, please suggest a mechanism to validate the second format(address:port) also. ----------------------------- #define INVALID -1 #define VALID 0 int validate IP(char *ipadd) What is the best & fastest way of validating an IPv4 address?

I find myself many times writing an Advanced Function that takes as its parameters only IP Addresses. Error: "An invalid IP address was specified."
