Yes, it's a simple webserver that hosts the EXE updates for our C.A.R.L. software.
If you visit the base address, it just checks that your IP isn't blocked.
But it also executes simple scripts to tell the calling *program* (not a human) whether there's a newer version of itself available to self-update from.
It's this that is being blocked by the EE Advanced Web Protection, so the customer needs a way of allowing all URLs on that IP though without interference from the EE product.
The only alternative I can think of is to disable Advanced Web Protection, which of course the customer isn't keen on as it performs a valid safety net for regular browsing.
