FOREWORD

ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of tele­communi­cations. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to stan­dard­izing telecommunications on a worldwide basis.

The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU‑T Study Groups which, in their turn, produce Recommendations on these topics.

The approval of Recommendations by the Members of the ITU‑T is covered by the procedure laid down in WTSC Resolution No. 1.

In some areas of information technology which fall within ITU-T’s purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.

NOTE

In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

INTELLECTUAL  PROPERTY  RIGHTS

The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.

As of the date of approval of this Recommendation, the ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

ITU-T  RECOMMENDATION

INFORMATION  TECHNOLOGY    OPEN  SYSTEMS  INTERCONNECTION 
NETWORK  SERVICE  DEFINITION

AMENDMENT  1
Addition of the Internet protocol address format identifier

1)          Subclause 2.3

Add a new reference:

      Internet Standard 00002, Assigned Numbers.

2)          Subclause A.5.2.1.2

In Table A.1, replace the second line, first column, 10-19, 20-29, 30-35, with:

 

10-19, 20-29, 30-33

 

Replace the third line, first column, 36-39, 40-49, 50-59, with:

 

34-39, 40-49, 50-59

 

Add a new row to the beginning of Table A.4:

 

IANA ICP

34

35

/////////////////////

/////////////////////

3)          New subclause A.5.2.1.2.8

Add a new subclause, A.5.2.1.2.8, after A.5.2.1.2.7:

A.5.2.1.2.8       Internet Protocol IDI format

The IDI consists of a 4-digit numeric code identifying an Internet Code Point (ICP) allocated according to Internet Assigned Number Authority (IANA) Internet Standard 00002, Assigned Numbers. The IANA ICP identifies a particular Internet Protocol (IP) addressing format.

4)          Subclause A.5.2.3

Add a new row to the end of Table A.5:

 

IANA ICP

34

17

/////////////////////

/////////////////////

5)          Subclause B.1

Add a new paragraph to the end of this subclause:

The IANA ICP format is included so as to allow for Internet Assigned Number Authority (IANA) to be an authority for the assignment of NSAP addresses and Group Network Addresses (GNAs) according to the hierarchy appropriate for the Internet (which is not always based on considerations of geographical or national boundaries). The IANA ICP identifies a particular Internet Protocol (IP) addressing format. The IANA ICP format is intended to support the assignment of NSAP and GNA addresses for use within Internet standards.
