Enumservices overview

ENUM entries can refer to various types of services. Clients use so called "Enumservices" to recognize which protocol or data type a certain ENUM entry points to. Those Enumservices are being registered in a list by the Internet Engineering Task Force (IETF). Currently, the following Enumservices are registered:

Besides those standardized Enumservices, "experimental" Enumservices can be used. Those services have their type name starting with "x-", and don't need to be registered by means of publishing a RFC. The registry at the IETF does not list those experimental Enumservices, though.
