I'm very new to WHM and cPanel, having been moved (by my request) from Plesk. My webhost gave me dedicated IPs for my two separate domains and instructed me to set them up in WHM. When I logged into WHM, it seems they were already set up, but I can only view one domain name/IP.

For example, my main site is something like www.mainsite.com with an IP of 123.45.678.100, and my second site is www.secondsite.com with an IP of 123.45.678.99. When I log into WHM, I can only view www.secondsite.com/123.45.678.99 and cannot view/change info for www.mainsite.com/123.45.678.100. What do I need to do to manage both these accounts? I assume I'm logging into the main site and that's why I can only see the second site, but I don't know for sure. Please help!

Thanks very much!
