HELP – LOOKUP Command

This command uses your DNS or Domain Name Server located at your ISP to translate a Host Name to an IP Address or vice versa. This utility is often referred to as a Name Server Lookup.

Enter an IP Address or Host Name in the Query Box. Then hit enter or click the Go! button.

Quick Tip:  You may use this command to scan all or part of a Class C IP Address. Replace the fourth octet with a ( * ) asterisk. For example: 204.71.177.*  A message box will appear asking for the IP range.  You may stop the query at any time by clicking the stop button or (ctrl c).
 
Your results will be displayed as following:

FORWARD Lookup:

      Host IP: 204.71.177.35
Host Name: yahoo.com
