Post IANA & RIR IPv4 Address Space Management Parties(/1), Cultures(/2), Sandboxes(/6), Silos(/12) Virtualized IPv☼ will add challenges and opportunities for more components in the Eco-System One bit, a 0 or a 1, allows Two Parties to be defined. {Democrat 0 , Republican 1} is one example. Two bits, 00 01 10 11, allow Four Cultures to be defined. [Unix 00 ,ISOC 01 ,FCC 10 ,ITU 11] is an example. http://www.ietf.org/mail-archive/web/rrg/current/msg06541.html =================================== 00 - UNIX 01 - ISOC, IETF, IRTF, IANA, ICANN, NANOG, RIRs... 10 - IEEE, ATSC, FCC, NTIA, NIST, LEOs... 11 - UN, ITU, ETSI... =================================== Parties & Cultures can be used to "Help" the Sandboxes have default stewardship. Example SandBox 4/6 4/6------------------------ {D} [UNIX] 016/8 Digital Equipment Corporation 1994-11 LEGACY {R} [ISOC] 017/8 Apple Computer Inc. 1992-07 LEGACY {D} [FCC] 018/8 MIT 1994-01 LEGACY {R} [ITU] 019/8 Ford Motor Company 1995-05 LEGACY ----------------------------- With XSLT and XML this table can be shown collapsed to 64 rows with Party & Culture labels. http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml Old traditions of a One Party Dictator remain ? http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.txt The U.S. FCC could step in and do the entire job of Post IANA & RIR stewardship. http://xkcd.com/195/ The ITU could also easily do the entire task. Binary does not change. One bit denotes Two 0 or 1. Two bits denote Four 00 01 10 11. With 6 bits (64) and 12 bits (4096) large blocks can be grouped for "stewardship" (i.e. management). Note: 3 bits could denote 8 Carriers....AT&T, Comcast....etc...they could also do the entire job.
