If you want a specific web site to listen on all IP addresses on your server:

Right-click the web site and select Properties.

For the IP Address field, select (All Unassigned).

Click OK.

If you want the web site to listen on only specific IP addresses:

Right-click the web site and select Properties.

Click the Advanced button next to the IP Address field.

Click Add.

Select the IP address and port number (default is port 80).

Leave the host header empty, unless multiple web sites will be sharing the same IP address.

Repeat this step for each IP address you would like to be bound to this web site.
