IANA Considerations for Network Layer Protocol Identifiers
Abstract
Some protocols being developed or extended by the IETF make use of
the ISO/IEC (International Organization for Standardization /
International Electrotechnical Commission) Network Layer Protocol
Identifier (NLPID). This document provides NLPID IANA
considerations.

1. Introduction
Some protocols being developed or extended by the IETF make use of
the ISO/IEC (International Organization for Standardization /
International Electrotechnical Commission) Network Layer Protocol
Identifier (NLPID).
The term "NLPID" is not actually used in [ISO9577], which refers to
one-octet IPIs (Initial Protocol Identifiers) and SPIs (Subsequent
Protocol Identifiers). While these are two logically separate kinds
of one-octet identifiers, most values are usable as both an IPI and
an SPI. In the remainder of this document, the term NLPID is used
for such values.
The registry of NLPID values is maintained by ISO/IEC by updating
[ISO9577]. The procedure specified by ISO/IEC in that document is
that an NLPID code point can be allocated without approval by
ISO/IEC, as long as the code point is not in a range of values
categorized for an organization other than the organization
allocating the code point and as long as ISO/IEC JTC1 SC6 is
informed.
This document provides NLPID IANA considerations. That is, it
specifies the level of IETF approval necessary for a code point to be
allocated for IETF use, the procedures to be used and actions to be
taken by IANA in connection with NLPIDs, and related guidelines.
[RFC5226] is incorporated herein except to the extent that there are
contrary provisions in this document.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
2. NLPIDs
[ISO9577] defines one-octet network layer protocol identifiers that
are commonly called NLPIDs, which is the term used in this document.
NLPIDs are used in a number of protocols. For example, in the
