Foreword
IS0 (the International Organization for Standardization) and EC (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, ISOAEC 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provide are considered to be no longer valid or useful.
ISOiTEC TR 11802-2, which is a Technical Report of type 3, was prepared by Joint
Technical Committee ISOmEC JTC 1, Informution technology, Subcommittee SC 6,
Telecommunications and information exchange between systems.
This Technical Report cancels and replaces ISOiTli 10735, of which it constitutes a
technical revision.
ISO/IEC 11802 consists of the following parts, under the general title Informution
technology - Telecommunications and information exchange between systems -
Local und metropolitan area networks - Technical reports and guidelines:
- Pari 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 ISO/IEC JTC 1
as new assignments are made.

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