vendor class
An administrative feature that allows DHCP clients to be identified and leased according to their vendor and hardware configuration type. For example, assigning a vendor class of HP to a printer vendor such as Hewlett-Packard would allow all Hewlett-Packard printers to be managed as a single unit so they could all obtain a similar DHCP leased configuration. See also Dynamic Host Configuration Protocol (DHCP); lease.

With virtual clusters, you can use different port rules for different Web sites or applications hosted on the cluster, provided each Web site or application has a different virtual IP address.

virtual server
A virtual computer that resides on a Hypertext Transfer Protocol (HTTP) server but appears to the user as a separate HTTP server. Several virtual servers can reside on one computer, each capable of running its own programs and each with individualized access to input and peripheral devices. Each virtual server has its own domain name and IP address, and each appears to the user as an individual Web site or File Transfer Protocol (FTP) site. Some Internet service providers (ISPs) use virtual servers for those clients who want to use their own domain names . Also called a Web site.
