I think he wan'ts to know how to configure a Web address. I would like to know that too, but my query is with an Intranet Address
you have to use apache virtual host to configure your sites <VirtualHost 10.1.2.3> ServerAdmin DocumentRoot /www/docs/host.foo.com ServerName host.foo.com ErrorLog logs/host.foo.com-error_log TransferLog logs/host.foo.com-access_log </VirtualHost> in that format
If you don't know how to edit these configuration files, it's best that you get a management system such as cpanel installed. It will save you a world of pain.
