1．简介
本文档描述了一种在测试IPv6的原型软件中IPv6地址的分配计划。这些地址都是临时的，在将来会被收回。任何使用这些地址的IPv6系统都得在未来的某个时候重新编号。这些地址在Internet中不能被正常路由，除了用来测试IPv6。
IPv6测试地址的地址格式跟"Aggregatable Global Unicast Address Allocation" [AGGR] 和 "TLA and  NLA Assignment Rules" [TLAASN]一致。
本文档时用来替换RFC 1897 "IPv6 Testing Address  Allocation"， January 1996.  RFC1897已经过时。
本文档中描述的地址跟IPv6  Addressing Architecture [ARCH]一致。它们可以手动地分配给节点，也可以通过IPv6 Auto Address Allocation [AUTO]或者 DHCP for IPv6 [DHCPv6]来分配。
关键字 "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", 和 "OPTIONAL" 在本文档中地解释参照[RFC2119]。

2．地址格式
Aggregatable Global Unicast Address格式在[AGGR]中定义如下：
| 3 |  13 |    32     |   16   |          64 bits               |
+---+-----+-----------+--------+--------------------------------+
|FP | TLA | NLA ID    | SLA ID |         Interface ID           |
|   | ID  |           |        |                                |
+---+-----+-----------+--------+--------------------------------+
其中：
FP=001=格式前缀
这是格式的前缀，用来识别Aggregatable Global Unicast Address。
TLA = 0x1FFE = Top-Level Aggregation Identifier
这是在IETF IPng Transition Working Group IPv6骨干网测试活动组的资助下，由IANA分配给IPv6骨干测试网的。这由IPv6骨干网活动组主席管理，目前是Bob Fink（rlfink@lbl.gov）。这个TLA的使用是临时的，所有使用这个TLA地址的用户都需要在将来某个时候重新编号。
NLA ID = Next-Level Aggregation Identifier
NLA ID空间是由TLA ID管理员分配的充分的地址层次空间，用来识别跟IPv6骨干网体系结构和拓扑结构的传输网络和终端用户位置。这可以提供一个多层次的传输服务，跟在IPv6骨干网上全面测试IPv6在真实使用环境下技术的目的一致。
SLA ID = Site-Level Aggregation Identifier
独立的结构用SLA ID这个字段产生本地网络的地址层次，并且用来识别子网。独立的机构要负责给这个字段分配值。
Interface ID
这是用来识别某些有关IPv6链路文档中（例如：[ETHER], [FDDI]等等）所定义的接口的接口标识符。

4．安全问题
本文档定义了一种跟[AGGR]相一致产生集合地址的方法。它对Internet网络设施的安全并无直接影响。IPv6分组的认证在中[AUTH]有定义。
