of those queries can be supplied with its own set of options, query class, query type and query options.
A global set of query options, which should be applied to all queries can also be supplied via global-d-
options.
These global query options must precede the first set of domain, class, type, options, and query options sup-
plied on the command line. Any global query options can be overridden by a query-specific set of query
options for each individual query.
For example:
dig +qr www.bind.org any -x 127.0.0.1 bind.org ns +noqr
