1. Comment - UN: US Should Not Control Internet

   (Jul 17, 2005 - 2:51 PM)

   Close, but not quite. In the first octet alone, the values 0, 127, 224-239 and 255 are "special". 0 and 255 are broadcast. 127 is loopback. 224-239 are multicast. These are special in the TCP/IP stack itself, so they can't be used for any other purpose. That means, 237*256^3 at minimum (3,976,200,192 addresses), and only if you don't care about internet connectivity. There are also at least 97 IANA Reserved address ranges in that first octet alone. Many can probably be assigned and used on the internet, but some can't.
