My Facebook application needs the IP Address of another user to communicate with that other user. So two users are using my application and one user wants to communicate with the other user. How does user A get the IP address of user B, or alternatively how does user B send its IP address to user A?
If this is not possible without passing the data manually is there a DB table that the IP address can be written to. My Facebook application has the ability to get its own local IP address. I just need a way to get the remote IP address using API’s.
Facebook don’t have support for any custom data storage, you will need to handle this on your own in your applications server code.
Basically you will need to have a database (or similar storage) where you store facebook user id and IP-address.
Another note is that you can’t get another Facebook users IP-address from Facebook, you need to get it from your connection to the user.
