Displays a short summary of nslookup subcommands.


  • The default DNS domain name is appended to a lookup request depending on the state of the defname and search options. The DNS domain search list contains the parents of the default DNS domain if it has at least two components in its name. For example, if the default DNS domain is mfg.widgets.com, the search list is named both mfg.widgets.com and widgets.com. Use the set srchlist command to specify a different list and the set all command to display the list.
