Virtual Subhosting is one of the most useful features of the Virtual Private Server. This feature allows you to support multiple domain names that each resolve to their own unique subdirectories on a single Virtual Private Server. In other words, you can host and on the same Virtual Private Server, each with its own domain name and unique site content. You can also offer each Virtual Subhost customer their own unique FTP login with access to their own subdirectory and e-mail addresses using their own domain name.

Subhosting Limitations

Virtual Subhosting has many advantages, but each subhost can create a load on your server. Because the traffic, content, and load generated by a Web site can vary significantly from one site to another, we can not give exact numbers of subhosts a single server can handle. You should be aware, however, that CGI scripts, dynamic content, and heavy traffic sites will need more of your VPS than simple static content sites.


Configuring Virtual Subhosts requires several steps, but is a generally easy task. The following links are provided to help guide you through the process. Server administrations can also use the CPX control panel to create new virtual hosts.

  • vaddhost

  • Manually Configuring Virtual Subhosts
