Which URL's are used by Xcode to communicate with Apple's servers

Question

I am looking to block the developer's machines to communicate with Apple servers.

Some places we need to communicate:

1. Adding an account
2. Validating certificate and auto signing
3. Validating Profiles
4. Uploading an .ipa to AppStore Connect
5. Anything else(legacy services?)...

Can anyone list the url's for the above services?

Answer 1

I used Charles to check the urls, this is what I found:

• https://devimages-cdn.apple.com
• http://ocsp.apple.com
• https://developerservices2.apple.com
• https://contentdelivery.itunes.apple.com
• http://ocsp.digicert.com
• https://gs-loc.apple.com
