A quick lookup can be done like this

Notice that I defined the server to use after the domain, an even quicker lookup would be by using the default nameserver of your windows system

Using a query type ‘any’ in non-interactive mode

By changing the parameter for -q= , different tyoes of records can be queried. like -q=mx or -q=A etc etc. The default behavior if -q is not specified is to query the A record.
