What are Azure Bot Framework and LUIS IP Addresses [for firewall rules]?

Question

I would like to open firewall rules for Microsoft LUIS and BotFramework. They both use TCP port 443, however I need the IP address ranges to unblock the business's firewall.

EDIT: Our Bot is written in NodeJS and hosted on-premises

2. You can setup a proxy to and add IP ranges to your firewall for your proxy.
