If you purchased your domain name through RadiusOnline, then your domain name will automatically renew as long as you pay your monthly invoices and have given us your updated billing information. If you can't remember whether you purchased your domain name through us, go to www.betterwhois.com, type in your domain name, and click "search." Under the Registrar and Administration field you will see the contact information. If the Registrar information says ENOM, Inc. and has RadiusOnline's contact information, then we purchased your domain name. If it has been registered elsewhere, then you will need to contact the administrator or Registrar to renew your domain name.
