我在哪里可以找到最后一个规范，它定义了 CIDR 中哪些 IP 地址对应于哪个大陆？
Where can I find the last specification defining which IP addresses correspond to which continent in CIDR?
我正在寻找定义大陆与 IP addresses 之间联系的规范（可能是 RFC）。我没有在 RFC 描述 CIDR 中找到它，我已阅读。
RFC1466 定义大陆和 IP 地址块之间的对应关系，但我不确定它实现到哪一点。
It is proposed that a broad geographic allocation be used for these
blocks. At present there are four major areas of address allocation:
Europe, North America, Pacific Rim, and South & Central America.
In particular, the top level block allocation be designated as follows:
Multi-regional 192.0.0.0 - 193.255.255.255
Europe 194.0.0.0 - 195.255.255.255
Others 196.0.0.0 - 197.255.255.255
North America 198.0.0.0 - 199.255.255.255
Central/South America 200.0.0.0 - 201.255.255.255
Pacific Rim 202.0.0.0 - 203.255.255.255
Others 204.0.0.0 - 205.255.255.255
Others 206.0.0.0 - 207.255.255.255
