You don't ned multiple IP addresses to do name-based virtual hosting (that's why it's called name-based as opposed to ip-based virtual hosting).

You might find the following pages useful: page 1, page 2 and page 3. You should start with apache docs, they explain the difference between ip-based and name-based virtual hosts which applies to every web server.
