U.S. Pat. No. 7,130,878
How it Works:
- Your new or existing domain is registered in the name of Domains By Proxy -- so their information is made public -- not yours.
- You retain full benefits of domain registration. You can cancel, sell, renew, or transfer your domain; set-up name servers for your domain; and resolve disputes involving your domain.
- The patented registration and email handling systems let you manage and control all postal mail and email addressed to the domain you have registered, as well as the domain's contact information.
- Your domain registration is safe and insured against loss.
- But don't even think about using a private registration to transmit spam, violate the law, or engage in morally objectionable activities.

* Plus domain registration fee. Private Registration will renew at the regular renewal rate.
