Use the NSLookup IP Address dialog to issue a z/OS Communications Server NSLOOKUP command to query name servers so that you can locate information about network nodes, examine the contents of a name-server database, or establish the accessibility of name servers.
The NSLookup IP Address dialog has two areas: a command input area where you specify the characteristics of the command you want to issue and the command output area where the results of the command are displayed.
The only required field is the Domain Name or Address field and it is prefilled with the IP address from the row or bar-graph bar from which you issued the take action command.
The remaining fields in this dialog box are prefilled with the default values when the dialog is initialized. You can change the value of any modifiable field before invoking the command. Field-level validation is performed before command execution. You are prompted by the dialog to correct invalid data.
Complete explanations of the fields in this dialog are found in the IBM z/OS Communications Server: IP System Administrator's Commands book for your level of z/OS. Brief explanations of these fields follow.
The retry algorithm for the NSLOOKUP command uses both the Retry value and the Timeout period. Each time a request is resent, the Timeout period for the request is twice the Timeout period used for the last attempt.
When you have completed the fields in the NSLookup IP Address dialog, click OK to issue the specified NSLOOKUP command. Click Cancel to close the NSLookup IP Address dialog. Click Help to invoke the online help.
