Wild card sub domains (*.yourdomain.com to point to yourdomain.com) can be achieved by placing the website on a dedicated IP address without any host headers. Thereafter wild card dns should be setup (* record) for given main domain which will point to this dedicated IP. Hence, all requests at given IP address will be routed to main website. If you want to achieve this, you will need to purchase dedicated IP address which is available at $36/yr. You will need to open a ticket with our sales team if you'd like to get this done.
