Run these commands from the Cortex XSOAR CLI
### dns-test-get-resolvers
Returns the nameserver IP addresses configured for the host (e.g. in /etc/resolv.conf)

### dns-test-resolve-domain
Queries all available resolvers for A, AAAA and CNAME records for the provided domain name and returns the results. Optionally increase the wait time for the query by passing a timeout value greater than 1
