cPanel Wildcard DNS Setup
Have you ever wanted to setup subdomains via your cPanel service, such that a keyword is the wildcard part of your domain? Something along the lines of:
* jacky.yourdomain.com
* johnny.yourdomain.com
* harry.yourdomain.com
You may be installing WordPress 3 to use the Multi Site features that will require wildcard DNS hosting. In any case your domain should be functioning and propagated before you attempt setting up a wildcard subdomain.
In cPanel Login to your account and look for your subdomain control panel applet.

Now you want to add a subdomain that will point to the location of your content. For WordPress 3.0 install choosing the directory with your .htaccess file as your target. If you only have one domain and site on your account you can point to your base public_html directory.
Click Create and you are ready to add subdomain hosting including WordPress 3.0 Website.
If you have problems because you are hosting many addon domains meaning many domain names with independent sites then you should make sure that the wildcard is pointing to the directory with WordPress 3.0 in it.
You will need to go into WordPress and enable your Network Options after you add your wildcard.
