I common limitation with popular domain registration companies is the limits they put on them. If you have your domain registered with godaddy, name.com or namecheap etc. You will need to buy hosting on top of them just to enable dns. A great feature with Thexyz Domain Manager
is that you will not need to. You get full dns control and free privacy protection. These features are not available with registrars like godaddy so this is just another you can save with Thexyz.
