1． 簡介
本文檔描述了一種在測試IPv6的原型軟件中IPv6地址的分配計劃。這些地址都是臨時的，在將來會被收回。任何使用這些地址的IPv6系統都得在未來的某個時候重新編號。這些地址在Internet中不能被正常路由，除了用來測試IPv6。
IPv6測試地址的地址格式跟"Aggregatable Global Unicast Address Allocation" [AGGR] 和 "TLA and NLA Assignment Rules" [TLAASN]一致。
本文檔時用來替換RFC1897 "IPv6 Testing Address Allocation"， January 1996. RFC1897已經過時。
本文檔中描述的地址跟IPv6 Addressing Architecture [ARCH]一致。它們可以手動地分配給節點，也可以通過IPv6 Auto Address Allocation [AUTO]或者 DHCP for IPv6 [DHCPv6]來分配。
關鍵字 "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", 和 "OPTIONAL" 在本文檔中地解釋參照[RFC2119]。


2． 地址格式
Aggregatable Global Unicast Address格式在[AGGR]中定義如下：
| 3 | 13 | 32 | 16 | 64 bits |
+---+-----+-----------+--------+--------------------------------+
|FP | TLA | NLA ID | SLA ID | Interface ID |
| | ID | | | |
+---+-----+-----------+--------+--------------------------------+
其中：
FP=001=格式前綴
這是格式的前綴，用來識別Aggregatable Global Unicast Address。
TLA = 0x1FFE = Top-Level Aggregation Identifier
這是在IETF IPng Transition Working Group IPv6骨干網測試活動組的資助下，由IANA分配給IPv6骨干測試網的。這由IPv6骨干網活動組主席管理，目前是Bob Fink（rlfink@lbl.gov）。這個TLA的使用是臨時的，所有使用這個TLA地址的用戶都需要在將來某個時候重新編號。
NLA ID = Next-Level Aggregation Identifier
NLA ID空間是由TLA ID管理員分配的充分的地址層次空間，用來識別跟IPv6骨干網體系結構和拓撲結構的傳輸網絡和終端用戶位置。這可以提供一個多層次的傳輸服務，跟在IPv6骨干網上全面測試IPv6在真實使用環境下技術的目的一致。
SLA ID = Site-Level Aggregation Identifier
獨立的結構用SLA ID這個字段產生本地網絡的地址層次，并且用來識別子網。獨立的機構要負責給這個字段分配值。
Interface ID
這是用來識別某些有關IPv6鏈路文檔中（例如：[ETHER], [FDDI]等等）所定義的接口的接口標識符。

4． 安全問題
本文檔定義了一種跟[AGGR]相一致產生集合地址的方法。它對Internet網絡設施的安全并無直接影響。IPv6分組的認證在中[AUTH]有定義。
