       options: -t<milliseconds>|--timeout <milliseconds>

       -w|--wait
              (always wait for queries to time out or fail)

       -b|--brackets
              (require [...] around IP addresses)

       -a|--address
              (always include [address] in output)

       Timeout  is  the  maximum  amount  to  delay any particular bit of output for.  Lookups will go on in the
       background.  Default timeout = 1000 (ms).
