is this a linux or windows?
You can add new host in to the hosts file of your computer.
In windows, look at C:\WINDOWS\system32\drivers\etc\hosts and in linux, I think it’s in /etc/hosts
In that file, add:
127.0.0.1 intranet
And you need to also map it in your apache httpd.conf like:
<VirtualHost 127.0.0.1>
ServerName intranet
DocumentRoot "C:/your/docroot"
</VirtualHost>
EDIT: oh and change apache to run in 80 port instead of 8080 if you want to use just http://intranet.. it’s set in the httpd.conf too.
Also google for more info on apache configuring.. there’s lots of things you can do with virtual hosts for example..
