Where can I find the last specification defining which IP addresses correspond to which continent in CIDR?

I'm looking for a specification (probably a RFC) defining the connection between continent and IP addresses. I didn't find it in the RFC describing CIDR that I have read.

Solution

  • RFC1466 define a correspondance between continents and IP address blocks but I'm not sure to which point it's implemented.

    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
