Controls whether to use the built-in DNS client.
This does not affect which DNS servers are used; just the software stack which is used to communicate with them. For example if the operating system is configured to use an enterprise DNS server, that same server would be used by the built-in DNS client. It is however possible that the built-in DNS client will address servers in different ways by using more modern DNS-related protocols such as DNS-over-TLS.
If you enable this policy, the built-in DNS client is used, if it's available.
If you disable this policy, the client is never used.
If you don't configure this policy, the built-in DNS client is enabled by default on MacOS, and users can change whether to use the built-in DNS client by editing edge://flags or by specifying a command-line flag.
