List of URLs needed by Orion

Some years ago I asked for a list of all URL's that Orion and it's modules want to have open: https://thwack.solarwinds.com/t5/NPM-Feature-Requests/List-of-all-internet-URL-s-needed/idi-p/569790 

I got no response from SolarWinds.

As of reason issues this brings up the question again. What URL's does Orion use? Can we get a "whitelist" please.
