Change Content Caching settings on Mac
On your Mac, use Content Caching settings to turn content caching on or off, choose the items you want cached, set the cache size and set up additional content caching options for your network. See Intro to content caching in Apple Platform Deployment.
To change these settings, choose Apple menu 
in the sidebar, click Sharing, then click 
next to Content Caching. (You may need to scroll down.)
Important: Each content cache must have either a local IP address that conforms to RFC 1918, or a non-RFC 1918 local IP address that is the same as its public IP address. Content caching is not supported on networks that use non-RFC 1918 addressing locally, and different non-RFC 1918 addressing publicly.
Local IP addresses that conform to RFC 1918 are in the following ranges:
10.0.0.0 to 10.255.255.255 (10/8 prefix)
172.16.0.0 to 172.31.255.255 (172.16/12 prefix)
192.168.0.0 to 192.168.255.255 (192.168/16 prefix)
Important: Content caching works only while your Mac is awake. To learn how to prevent your Mac from going to sleep, see Set sleep and wake settings. To keep a headless computer awake, you can use the caffeinate command line utility in Terminal.
