nslookup

Synopsis

                  nslookup [-option...] [host_to_find | -[server ]]

TCP/IP command. Query Internet domain name servers. nslookup is deprecated; its functionality is replaced by the dig and host commands. nslookup may not be included in some distributions.

nslookup has two modes: interactive and noninteractive. Interactive mode allows the user to query name servers for information about various hosts and domains or to print a list of hosts in a domain. It is entered either when no arguments are given (default name server will be used) or when the first argument is a hyphen and the second argument is the hostname or Internet address of a name server. Noninteractive mode is used to print just the name and requested information for a host or domain. It is used when the name of the host to be looked up is given as the first argument. Any of the keyword=value pairs listed under the interactive set command can be used as an option on the command line by prefacing the keyword with a -. The optional second argument specifies a name server.

Options

All of the options under the set interactive command can be entered on the command line, with the syntax - keyword[= value].

Interactive commands
