Entering the interactive mode

Interactive mode can be used to repetitively query one or more name servers for information about various hosts and domains, to display that information on the console, and, in some cases, to write response data to a file.

You can enter the interactive mode under the following conditions only:

No arguments are supplied on command invocation or the -v option is specified; the default name server is used.
The first argument is a hyphen, and the second argument is the host name or Internet address of a name server.
