A network tool that lets you obtain information on host names and IP addresses. This information also includes possible aliases.

You can use the Lookup tool to:

• Look up a host name from an IP address.
• Find the IP address from a host name.

To use the Lookup tool, do the following:

1. Select the Lookup tab.
   
   
2. In the Host text box, enter a host name or IP address of the host you want to look up (for example, microsoft.com).
   
   The drop-down list shows the previous host names or IP addresses for which you've done a lookup.
   
   
3. Click the Start button.
   
   The Lookup tool displays the results of the query in the Response area.
   
   During the query, the Start button toggles to Stop. You can click Stop at any time to stop the query.

Note:

Lookup requires a connection to a network with a DNS or a WINS server or other type of name server. Your computer must be configured to access the DNS.
