Option Settings

nslookup has its own set of dials and knobs called option settings. All the option settings can be changed. We’ll discuss here what each of the options means. We’ll use the rest of the chapter to show you how to use them.

C:\> nslookup 
Default Server:  terminator.movie.edu 
Address:  192.249.249.3 

> set all 
Default Server:  terminator.movie.edu

  novc
  noignoretc
  port=53
  type=A
  class=IN
  timeout=2
  retry=1
  root=A.ROOT-SERVERS.NET.
  domain=movie.edu
  MSxfr
  IXFRversion=1
  srchlist=movie.edu

> ^Z

The options come in two flavors: Boolean and value.

As you might guess, the option search is on.

How you change Boolean or value options depends on whether or not you are using nslookup interactively. In an interactive session, you change an option with the set command, as in set debug or set domain=classics.movie.edu. From the command line, you omit the word set and precede the option with a hyphen, ...
