The tutorial shows you how to store variables in a file. Due to the fact that the IP also is a variable, you can just replace the values that are needed in a registration with the IP.

But because you just want to save an IP into one file, I would furthermore suggest the file-functions fopen, and fwrite. If you ask yourself which mode you should chose for fwrite, in my opinion IO_APPEND would make sense in this case.
