The Virtual hosts can be “IP-based” or “name-based”. It means that every website can have a different IP address or multiple names can be running on each IP address. The fact that they are running on the same physical server is not apparent to the end user. The Virtual Host section contains the information like Website name, Server Admin Email, ErrorLog File location, Directory Index, Document root, etc. It refers to the practice of running more than one website on a single machine.
