Re: The Mathematical Reality of IP Addressin in IPv4...

SUMMARY of
http://www.ietf.org/internet-drafts/draft-terrell-math-ipaddr-ipv4-00.txt

By distinguishing apparently identical IP addresses by using different
subnet masks one can increase the number of IP addresses distinguishable by
a 32-bit number to greater than 2^32.

Except for the problem that you need 32 extra bits to carry a mask or 5
extra bits to carry the masklen.

IETF should have waited until 2000/04/01 before posting this.
