Currently I have my DNS servers pointed to 22.214.171.124 and 126.96.36.199 (DHCP server hands these out). My macOS server has caching service turned on. Do I need to have my DHCP server hand out the IP address of my macOS server (and then forward DNS lookups?) for clients to be able to use the caching service? Or will clients automatically detect the caching service on the network and use it regardless of which address the DNS entry is pointed to?
