Hello,
I need help locking my application to one IP address, so I would write the IP address inside the program. Any ideas how i would get the clients IP to compare to the one hard coded inside the application. Sorry for my bad english! :)

Which operating system?

You may also ask your preferred search machine using "c++ [your OS] detect client IP" to get lot of examples which should be basically all the same for a specific OS.

What is the purpose of the IP address in your program?

Solution 2

Considering IP addresses for clients usually change over time this is a really bad idea and limits the usefulness and supportability of the application.

Solution 1

It is not an good idea. For secure access you should use encryption like https or some vpn.

If you really want to hard code your IP you should to some math to calculate it from some constants.

To get your local ip address look at this example code.
