1.1. Internet Registries and Interoperability on the Internet
Internet registries hold identifiers consisting of constants and
other well-known values used by Internet protocols. Such values
define a common vocabulary that protocols understand when
communicating with each other. For example, the TCP port number of
"80" is globally understood to denote "http" service. Almost every
protocol in existence makes use of registries in some form.
Internet registries are critical to the operation of the Internet.
They are needed to record the definitive value and meaning of
identifiers that protocols use when communicating with each other.
Management of Internet registries must be done in a predictable,
stable and secure manner in order to ensure that protocol identifiers
have consistent meanings and interpretations across all
implementations and deployments.
Protocol identifier values can be numbers, strings, addresses, and so
on. They are uniquely assigned for one particular purpose or use.
They can be maintained in centrally maintained lists (such as, for
instance, lists of cryptographic algorithms in use in a particular
protocol) or hierarchically allocated and assigned by separate
entities at different points in the hierarchy (such as for IP
addresses and domain names). At the time of writing, the Internet
Assigned Numbers Authority (IANA) maintains over one thousand
protocol parameter registries.
Stable and predictable assignment and registration of protocol
identifiers for Internet protocols is of great importance to many
stakeholders, including developers, vendors, and customers, as well
as users of devices, software, and services on the Internet. These
stakeholders use and depend on registries and implicitly trust the
registry system to be stable and predictable. The registry system is
built on trust and mutual cooperation; the use of the registries is
voluntary and is not enforced by mandates or certification policies.
Stability and consistency of Internet registries is achieved through
the definition of appropriate and clear policies for making additions
to or updating existing entries. Such policies must take into
account the technical and operational properties of the technology
that makes use of the registries. At the same time, it must be
