Answer 1

You can do this. There are different possibilities depending on the pricing tier. From not possible at all, to possible but may change, to possible and guaranteed that IP address will not change.

The bad news is that, possible and guaranteed that IP address will not change, requires using the isolated tier.

See: https://docs.microsoft.com/en-us/azure/azure-functions/ip-addresses#dedicated-ip-addresses

Answer 2

I suggest you look into using service tags: https://docs.microsoft.com/en-us/azure/virtual-network/service-tags-overview#available-service-tags
