I believe it's officecdn.microsoft.com but it probably varies based on region and entity (government vs educational vs business).

If it's a bandwidth issue you can download the updates once and configure the clients to pull from a local server. See https://docs.microsoft.com/en-us/deployoffice/configure-update-settings-for-office-365-proplus

Got this from ms support:

If you don’t’ want to let user to download office updates from your internal network, we are not recommend to block URL to achieve it, since the activation and installation are also using the URL officecdn.microsoft.com.

You can try to block following URL, because these are the default CDNURl for different update channel.
