What happened to draft-hain-1918bis-01, which tried to get more
address space for private Internets, but expired back in 2005?
I see the point about regarding 240.0.0.0/4 as "tainted space" and
therefore being less than useful on the public Internet.....
RFC 3330 listed as not currently part of the public Internet:
0.0.0.0/8 "this" 16,777,216
10.0.0.0/8 "private" 16,777,216
127.0.0.0/8 "loopback" 16,777,216
169.254.0.0/16 "link-local" 65,536
172.16.0.0/12 "private" 1,048,576
192.0.2.0/24 "test-net" 256
192.168.0.0/16 "private" 65,536
192.18.0.0/15 "benchmark" 131,072
224.0.0.0/4 "multicast" 268,435,456
240.0.0.0/4 "reserved" 268,435,466
-------------
587,569,816 (13.68% of total non-public)
4,294,967,296 (total)
3,707,397,480 (addresses public)
Some larger providers and private organizations who depend upon
private IPv4 addresses have complained there is no suitably large
"private" IP address range which can assure each user within their
network can obtain a unique private IP address. It would seem class
E could, and might already, function as a larger "private" IP address
range.
