Your organization deployed one Mac mini to cache content for devices on several subnets.

Apple’sContent Cachingservice reduces internet bandwidth by storing software updates, apps, and iCloud content locally. In multi-subnet environments, admins can refine caching behavior using advanced options. Apple documentation highlights that to optimize across subnets, you can configure caching to includecustom local networks(B) so devices beyond a single LAN can retrieve cached data. Additionally, caches can be configured toshare peers across custom local networks(D), allowing multiple caches or subnet groups to collaborate. Options limited to the same local network or public IP are less flexible, and do not optimize cross-subnet bandwidth utilization.
