Description of issue

My company blocks outbound internet on servers. I have a Mac Mini that has an AMP (Apache, MySQL, PHP) setup and I want to move to using Homebrew to install PHP and Apache HTTPD. I have Homebrew installed on the Mac Mini, but I can't run "brew update" since the URLs that Homebrew is calling are blocked. Would someone provide the URLs needed by Homebrew when running "brew update" and "brew install php apache"? (so far I am seeing https://formulae.brew.sh and https://ghcr.io) Thank you!

formulae.brew.sh and ghcr.io will get you most of the way with a standard install. This will allow you run brew update and upgrade any formulae that we have bottles for.

can someone please post a comprehensive list of hostnames?

No such list exists within the open source project, and it seems clear here that nobody is volunteering the effort to create one.
