Using Unity Behind proxy

Hello!

We are working in big company and we are behind proxy.
We cannot disable it but we can add rules for specific ip addresses and protocols.

Can somebody give me a list with all ip addresses for Unity and Unity services like UCB, Analytics, Package Manager?
I tried new beta 2018 and I cannot open project with shader system because Unity cannot download packages from com.unity.*.

I finally was able to do it!

I have to setup few variables:

Right now Package Manager and Unity hub is working!
