What is domain parking?
In order to register a domain name for your use it must have at least two nameservers who are willing to answer for it. When your domain is used for email or any other purpose, these nameservers are usually provided by your ISP as part of your service fee. Parking implies that you do not plan to use your domain right away. However, you still need to have nameservers willing to answer for the domain. We allow you to use our nameserver free of charge for this purpose.
