The 1997 Amendment 1 to ITU-T Rec. X.213 | ISO/IEC 8348 was made to enable an address whose format is identified by an IANA Internet Code Point (ICP) to be carried in an NSAP address. The IANA Internet Code Point carried in the Initial Domain Identifier (IDI) is used to identify the particular Internet Protocol addressing format of the IP address that is carried in the Domain Specific Part (DSP) of the NSAP.

A review of the text of Amendment 1 to Rec. X.213 | ISO /IEC8348 indicates that the text requires clarification. It is the intention of SG 7 to revise the text of Rec. X.213 | ISO/IEC 8348

To make the text more user friendly it has been suggested that the most relevant 4 digit numeric IANA ICP codes could be listed in the text of the Recommendation. In particular ICPs for IPV4 and IPV6 addresses are considered to be essential information that should be listed.

We wished to know the values of the Internet Code Points that have been allocated to the IPV4 and IPV6 address formats and an authoritative reference to where the codes are listed. If allocations of ICPs have not yet been made to IPV4 and IPV6 address we request this action be undertaken.

Attached is Amendment 1 to Rec. X.213 | ISO/IEC 8348.

Any comments in regard to revising the text of Amendment 1 to X.213 would be appreciated.

Attachment: Amendment 1 to ITU-T Rec. X.213
