Some friends asked, does Go Daddy support Pan-Domain? Or does IX Web Hosting support Pan-Domain? No, they don't support directly. Because GD and IX limited this permission, we can't add a subdomain which names * on the hosting control panel. If you need to realize Pan-Domain at GD or IX, you should use the delicated IP to realize Pan-Domain.
If your hosting uses cPanel as the hosting control panel, congrats, this hosting supports Pan-Domain. You can add a subdomain: * , then your hosting can support Pan-Domain.
