Such a system is very wasteful for your server resources as you would need individual servers with Apache installed for every single domain you want to host. Name-based or virtual hosting is used to host multiple domains on the same Apache web server. If a number of different domain names have already been assigned to your Apache web server's IP address using a DNS server or through a local /etc/hosts file, virtual hosts can be configured for every available domain name to direct the user to a specific directory on the Apache server containing the site's information.
