Domains by Proxy is an Internet company owned by Go Daddy CEO Bob Parsons. It offers domain privacy services through partner domain registrars such as Go Daddy and Wild West Domains.

Subscribers list Domains by Proxy as their administrative and technical contacts in the Internet's WHOIS database, thereby delegating responsibility for managing unsolicited contacts from third parties. Since most of such contacts originate from spammers, domain owners experience little downside other than subscription fees. The same cannot be said for the general public, however, when the domain owners being shielded are spammers.

Domains by Proxy does not offer true anonymity. In most countries they are legally obliged to collect personal information from domain owners. They also require little persuasion to release domain owners' contact information, in some cases requiring only a phone request, certified letter to the domain owner, or a cease and desist letter.
