Apache Reference: http_core, NameVirtualHost

NameVirtualHost

Declare a Name-based Virtual Host
Syntax: NameVirtualHost host[:port]
Example: NameVirtualHost 192.168.1.1
Since: Apache 1.3

This directive is required if you want to configure name-based virtual hosts. Although host can be a host name or an IP address, it is recommended that you always use an IP address only. With this directive, you specify the address to which your name-based virtual host names will resolve. If you have multiple name-based hosts on multiple addresses, repeat the directive for each address. Notice that the ``main server'' and any ``_default_'' servers will never be served for a request to a NameVirtualHost IP address.
