I have to run an app on the cloud with a firewall that has a domain whitelist. In other words: I have to know all the domains necessary for installing packages like Plots.jl or ModelingToolkit.jl. I’m not sure how the package server works. Is it enough to whitelist [pkg.julialang.org](http://pkg.julialang.org)?

I think you’ll need to whitelist everything listed in the “Official Domains” section at the bottom of the page here: [Download Julia](https://julialang.org/downloads/#official_domains)
