The first byte is the version (0x04), then come the address bytes and finally an unsigned short for the port. but I have failed using IP address to int32 if inent_aton what should I have to do!! It is saying that 192.168.25.20 is 3f 57 e6 eb in raknet P.S. I succeeded to do with port but I can't handle the IP address HELP PLEASE!!
