Route can be added to IP addresses, or ranges, not urls…
Do it and setup your own paid subscription and you will be very rich. The demand for this as a supported package is huge.
This ends up being the problem then. From my understanding these IPs can change, so having a DNS name would be ideal. I’ve looked before, but can’t seem to find a CIDR block for endpoints that AWS would possibly use. If so, I bet it’s a huge block.
