Abstract

This document describes an allocation plan for IPv6 addresses to be used in testing IPv6 prototype software. These addresses are temporary and will be reclaimed in the future. Any IPv6 system using these addresses will have to renumber at some time in the future. These addresses will not to be routable in the Internet other than for IPv6 testing.

IPv6 Testing Address Allocation

Status of this Memo

This document specifies an Experimental protocol for the Internet

community. This memo does not specify an Internet standard of any

kind. Discussion and suggestions for improvement are requested.

Distribution of this memo is unlimited.

1.0 Introduction

This document describes an allocation plan for IPv6 addresses to be

used in testing IPv6 prototype software. These addresses are

temporary and will be reclaimed in the future. Any IPv6 system using

these addresses will have to renumber at some time in the future.

These addresses will not to be routable in the Internet other than

for IPv6 testing.

The addresses described in this document are consistent with the IPv6

Addressing Architecture [ARCH]. They may be assigned to nodes

manually, with IPv6 Auto Address Allocation [AUTO], or with DHCP for

IPv6 [DHCPv6].

2.0 Address Format

The address format for the IPv6 test address is consistent with the

provider-based unicast address allocation [PRVD] which is as follows:

| 3 | 5 bits | 16 bits | 8 | 24 bits | 8 | 64 bits |

+---+----------+----------+---+------------+---+----------------+

|010|RegistryID|ProviderID|RES|SubscriberID|RES|Intra-Subscriber|

+---+----------+----------+---+------------+---+----------------+

The specific allocation of each field of the test address format is

as follows:

| 3 | 5 bits | 16 bits | 8 | 24 bits | 8 | 16 bits|48 bits|

+---+----------+----------+---+------------+---+--------+-------+

| | |Autonomous| | IPv4 | | Subnet | Intf. |

|010| 11111 | System |RES| Network |RES| | |

| | | Number | | Address | | Address| ID |

+---+----------+----------+---+------------+---+--------+-------+

where:

010

This is the Format Prefix used to identify provider-based

unicast addresses.

11111

This is a Registry ID reserved by the IANA. The initial use of

addresses in this Registry ID for IPv6 testing is temporary.

All users of these addresses will be required to renumber at

some time in the future.

Autonomous System Number

This is the current autonomous system number assigned to the

provider providing internet service to the an IPv6 testers

organization. For example for IPv6 testers receiving internet

service from BBN Barrnet would use autonomous system number 189.

This would be coded in the autonomous system field of the

address as follows:

0000 0000 1011 1101 (binary)
