Is there any keyword replacement for the IP address of the user browsing the website?
Only way to check someone's IP/hostname in matrix is to use a show_if with a server condition for $_SERVER['REMOTE_ADDR'] in a design parse file
I need to use this in conjunction with the remote content asset. I need to pass the IP of the user browsing the page to the remote page.
No, there isn't.
Unfortunately, this is not possible.
