IPv6 Testing Address Allocation

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.''
Please check the 1id-abstracts.txt listing contained in the internet-
drafts Shadow Directories on nic.ddn.mil, nnsc.nsf.net,
nic.nordu.net, ftp.nisc.sri.com, or munnari.oz.au to learn the
current status of any Internet Draft.
This draft expires in January 17, 1998.
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 address format for the IPv6 test address is consistent with the
"Aggregatable Global Unicast Address Allocation" [AGGR] and "TLA and
NLA Assignment Rules" [TLAASN].

INTERNET-DRAFT IPv6 Testing Address Allocation July 16, 1997
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
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 Aggregatable Global Unicast Address Allocation format defined in
[AGGR] is as follows:
| 3 | 13 | 32 | 16 | 64 bits |
+---+-----+-----------+--------+--------------------------------+
|FP | TLA | NLA ID | SLA ID | Interface ID |
| | ID | | | |
+---+-----+-----------+--------+--------------------------------+
where:
FP = 001 = Format Prefix
This is the Format Prefix used to identify aggregatable
global unicast addresses.
TLA = 0x1FFE = Top-Level Aggregation Identifier
This is a TLA ID 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 (currently Bob Fink <rlfink@lbl.gov> ).
The use of this TLA ID is temporary. All users of these
addresses in this TLA ID will be required to renumber at some
time in the future.
NLA ID = Next-Level Aggregation Identifier
The NLA ID space will be assigned, by the TLA ID
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 ID = Site-Level Aggregation Identifier
The SLA ID field is used by an individual organization to
create its own local addressing hierarchy and to identify
subnets. Assignment of the SLA ID 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 <link> document, such
as [ETHER], [FDDI], etc.

5.0 Security Considerations
This document defines a test approach for creating aggregatable
address consistent with [AGGR]. It does not have any direct impact
on Internet infrastructure security. Authentication of IPv6 packets
is defined in [AUTH].
