What is Public User ENUM?
With Public User ENUM (also called “End User ENUM”), the end user can provision his or her records in the ENUM registry in the public domain e164.arpa. In other words, the end user is the registrant for the ENUM domain name within the domain e164.arpa; the implication is that the end user has “opted in” to the ENUM service. “End User opt in” is generally considered a good policy if end user data is publicly available on the Internet.
