Postel, ISI IPv6 Testing Address Allocation <draft-ietf-ipngwg-testv2-addralloc-00.txt> Status of this Memo This document is an Internet Draft. Internet Drafts are working documents of the Internet Engineering Task Force (IETF), its Areas, and its Working Groups. Note that other groups may also distribute working documents as Internet Drafts. Internet Drafts are draft documents valid for a maximum of six months. Internet Drafts may be updated, replaced, or obsoleted by other documents at any time. It is not appropriate to use Internet Drafts as reference material or to cite them other than as a ``working draft'' or ``work in progress.''

This draft expires in November 27, 1997. 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. This document is intended to replace RFC1897 "IPv6 Testing Address Allocation", January 1996. RFC1897 will become historic. The addresses described in this document are consistent with the IPv6 draft-ietf-ipngwg-testv2-addralloc-00.txt [Page 1] INTERNET-DRAFT IPv6 Testing Address Allocation May 27, 1997 Addressing Architecture [ARCH]. They may be assigned to nodes manually, with IPv6 Auto Address Allocation [AUTO], or with DHCP for IPv6 [DHCPv6]. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119]. 2.0 Address Format The address format for the IPv6 test address is consistent with the aggregatable global unicast address allocation [AGGR] which is as follows: | 3 | 13 | 32 | 16 | 64 bits | +---+-----+-----------+--------+--------------------------------+ |FP | TLA | NLA* | SLA* | Interface ID | +---+-----+-----------+--------+--------------------------------+ where: FP = 001 = Format Prefix This is the Format Prefix used to identify aggregatable global unicast addresses. TLA = 0x1FFE = Top Level Aggregator This is a TLA assigned by the IANA for 6bone testing under the auspices of the IETF IPng Transition Working Group 6bone testbed activity. It is to be administered by the chair of the 6bone activity (Bob Fink at the present time). The use of this TLA is temporary. All users of these addresses in this TLA will be required to renumber at some time in the future. NLA* = Next-Level Aggregator(s) The NLA* space will be assigned, by the TLA administrator, in an addressing hierarchy sufficient to identify transit networks and end user sites consistent with the architecture and topology of the 6bone. This will provide a multi-level transit service consistent with the 6bone goals of fully testing IPv6 technology in real use environments. SLA* = Site-Level Aggregator(s) draft-ietf-ipngwg-testv2-addralloc-00.txt [Page 2] INTERNET-DRAFT IPv6 Testing Address Allocation May 27, 1997 The SLA* field is used by an individual organization to create its own local addressing hierarchy and to identify subnets. Assignment of the SLA* field is the responsibility of each individual organization. Interface ID This is the interface identifier of the interface on the link as defined in the appropriate IPv6 over document, such as [ETHER], [FDDI], etc. 4.0 References [ARCH] Hinden, R., "IP Version 6 Addressing Architecture", Internet Draft,, May 1997.
