Our Free DNS service can be used as a backup only for the domains that are not registered with us.
Firstly, you need to point your domain to our Free DNS nameservers at your current Registrar. They are:
freedns1.registrar-servers.com
freedns2.registrar-servers.com
freedns3.registrar-servers.com
freedns4.registrar-servers.com
freedns5.registrar-servers.com
