How is my IP Address Control will look?

Just go in and add those 3 IP addresses to the allowed list, and change the order to allow/deny (as rrinc said). Allow/deny: "access is denied by default and is allowed only if the client IP address is in the Allowed IP Addresses list and is not in the Denied IP Addresses list".
You may want to take note here, though. If one of your member's IP address changes, they won't have access anymore. Only people with static IP addresses won't change. It costs a bundle to get one of those. Also, they can only view your site from their default internet connection. For the average person, Abyss' user interface will keep any unauthorized viewers away.
