The DNS Resolver resolves queries incoming directly from Abilis.

The example below shows how to configure the DNS Resource as Resolver.

[16:37:46] ABILIS_CPX:s p dns act:yes primary:62.94.0.1 secondary:62.94.0.2

	To activate the changes made on the upper case parameters, execute the initialization command init res:dns.; while to set act the changes made on the lowercase parameters a save conf and an Abilis restart are required (i.e. With warm start command).

In the example above, CACHING is enabled (CACHE:YES): responses are stored in cache a period which depends on the size of the cache (cache-size parameter).

Use the following command to display DNS CACHE:

[16:39:44] ABILIS_CPX:d dns cache
