1.  Introduction

   The Internet Engineering Task Force (IETF) and its predecessors have
   traditionally separated the publication of protocol specifications in
   immutable Request for Comments (RFCs) and the registries containing
   protocol parameters.  Traditionally, the registries are maintained by
   a set of functions known collectively as the Internet Assigned
   Numbers Authority (IANA).  Dating back to the earliest days of the
   Internet, specification publication and the registry operations were
   tightly coupled: Jon Postel of the Information Sciences Institute
   (ISI) of the University of Southern California (USC) was responsible
   for both RFC publication and IANA registry operation.  This tight
   coupling had advantages, but it was never a requirement.  Indeed,
   today the RFC Editor and IANA registry operation are provided by
   different entities.

   Internet registries are critical to the operation of the Internet,
   because they provide a definitive record of the value and meaning of
   identifiers that protocols use when communicating with each other.
   Almost every Internet protocol makes use of registries in some form.
   At the time of writing, the IANA maintains more than two thousand
   protocol parameter registries.

   Internet registries hold protocol identifiers consisting of constants
   and other well-known values used by Internet protocols.  These values
   can be numbers, strings, addresses, and so on.  They are uniquely
   assigned for one particular purpose or use.  Identifiers can be
   maintained in a central list (such as a list of cryptographic
   algorithms) or they can be hierarchically allocated and assigned by
   separate entities at different points in the hierarchy (such as IP
   addresses and domain names).  To maximize trust and usefulness of the
   IANA registries, the principles in this document should be taken into
   consideration for centralized registries as well as hierarchically
