Foreword
IS0 (the International Organization for Standardization) and IEC (the
International Electrotechnical Commission) form the specialized system for
worldwide standardization. National bodies that are members of IS0 or
IEC participate in the development of International Standards through
technical committees established by the respective organization to deal
with particular fields of technical activity. IS0 and IEC technical
committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with IS0 and
IEC, also take part in the work.
In the field of information technology, IS0 and IEC have established a joint
technical committee, ISO/IEC JTC 1.
The main task of technical committees is to prepare International
Standards, but in exceptional circumstances a technical committee may
propose the publication of a Technical Report of one of the following types:
type 1, when the required support cannot be obtained for the publication
of an International Standard, despite repeated efforts;
type 2, when the subject is still under technical development or where
for any other reason there is the future but not immediate possibility of
an agreement on an International Standard;
type 3, when a technical committee has collected data of a different
kind from that which is normally published as an International Standard
('state of the art', for example).
Technical Reports of types 1 and 2 are subject to review within three years
of publication, to decide whether they can be transformed into International
Standards. Technical Reports of type 3 do not necessarily have to be
reviewed until the data they provide are considered to be no longer valid or
usef ul.
ISOAEC TR 11802-2, which is a Technical Report of type 3, was prepared
by Joint Technical Committee ISOAEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange
between systems.
This second edition cancels and replaces the first edition (ISOAEC TR
11 802:1995), which has been technically revised.
ISOAEC 11802 consists of the following parts, under the general title
Information technology - Telecommunications and information exchange
between systems - Local and metropolitan area networks - Technical
reports and guidelines:
- Part I: The structure and coding of Logical Link Control addresses in
Local Area Networks [Technical Report]
- Part 2: Standard Group MAC Addresses [Technical Report]

Introduction
The Standards for LANs generally comprise the physical layer, the medium
access control (MAC) sublayer, and the logical link control (LLC) sublayer.
In OS1 terminology, the MAC and LLC sublayers are considered to be
sublayers of the OS1 Data Link layer. Both the MAC and LLC sublayers
contain fields for addressing.
A Universally Administered Address Block has been allocated for the
assignment of Group MAC Addresses for use in Standards. This Technical
Report contains a description of the MAC addressing conventions, the
criteria which will be used by ISOAEC when considering a request for an
assignment, and a record of assignments.
This Technical Report will be kept up to date by ISOAEC JTC 1 as new
assignments are made.

4 Binary and Hexadecimal Representation of LAN MAC Addresses
The Hexadecimal (in hexadecimal) Representation of LAN MAC addresses has been defined in
ISO/IEC 10039 and is used throughout this Technical Report.

Representations.

Figure 1 - Representation of LAN MAC Addresses
The 48-bit address (universal or local) is represented as a string of six octets. The octets are
displayed from left to right, in the order that they are transmitted on the LAN medium, separated by
hyphens. Each octet of the address is displayed as two hexadecimal digits. The bits within the octets
are transmitted on the LAN medium from left to right. In the Binary Representation the first bit
transmitted, of each octet, on the LAN medium is the least significant bit of that octet. The
IndividuaVGroup address bit is the least significant bit. The left-most bit of the Binary Representation
(IndividuaVGroup address bit) of a MAC address distinguishes individual from group add
