Most shared hosting services store your files and databases on a the same server with the same IP address. However, LunarPages has recently stopped that practice and keeps some people’s databases on different servers with different IP address. This makes it more difficult to install Wordpress on LunarPages.
If you’re a LunarPages customer and trying to figure out what the IP address of your databases is, it’s very likely NOT the same as the IP address of your Lunar Pages Control Panel (LPCP).
