IPv8 is intended to be a work-in-progress. It starts with IPv4 and evolves it. Anyone canthen participate, unlike IPv6, which excludes people. You are welcome to add to theIPv8 melting pot. NAT is an integral part of the IPv8 approach. Many said that NAT wouldnot be useful or would not work. Some of those people are I* society leaders. It is their wayor the highway. Many have chosen the highway....and route around the situation...China can...You can....We can....Before you worry about the protocol, it is important to work out the transitions and theaddress space architecture. The 32-bit IPv4 addresses can be expanded, without changingIPv4. IPv8 assumed from the start that people would likely have one 32-bit site-id fortheir gateway. That is now coming to pass with DSL and cable modem services offeringT1 speeds for less than $50 per month. This year's 2002:[IPv4] approach to addressingwas a start to get people's feet wet. People now want more features in the 128-bit DNSservices, and still remain connected to the Internet. They write the code to do that, andtest it on the existing Internet.128-bit (AAAA) DNS Flag Day Format[YMDD]:[16-bits for the outer header]:[IPv4]:[48-bit Persistent Address+Port]The 16-bits for the outer header are...1-bit to set the "Spare" bit [S]1-bit to set the Don't Fragment (DF) bit [D]2-bits to select 1 of 4 common TTL values (8, 32, 128, 256) [LL]1-bit to set No Options Supported [O]7-bits to set the Identification Field(dst) [FFFFFFF]4-bits to set the TOS(dst) field [TTTT]SDLL.OFFF.FFFF.TTTTGiven an AAAA DNS record, an IPv8 or IPv16 node can then specify,a Flag Day [YMDD] to start using this particular record, an IPv4 addressfor the site's gateway/firewall, 11 bits of extended IPv4++ addressing bits,plus the spare bit can be controlled, the DF bit, and 4 common TTL valuescan be recommended. Finally, the node can mark that it wants to notsupport Options on the IPv4 encapsulating header. The node can also ofcourse include it's 48-bit persistent address and optional 16-bit Port value.Note, there is only one "Spare" bit, it is not a [src][dst] arrangement.It can be used to toggle traffic from one net layer to another, and not allowtraffic to flow between those layers. Traffic can be split at each side of thelegacy core IPv4 network, based on that bit.Jim Fleming2002:[IPv4]:000X:03DB:...IPv8 is closer than you think...IPv16 is even closer...http://ipv8.dyndns.tvhttp://ipv8.yi.orghttp://ipv8.dyns.cxhttp://ipv8.no-ip.comhttp://ipv8.no-ip.orghttp://ipv8.no-ip.bizhttp://ipv8.no-ip.infohttp://ipv8.myip.ushttp://ipv8.dyn.eehttp://ipv8.community.net.auhttp://www.iana.org/assignments/ipv4-address-spacehttp://www.ntia.doc.gov/ntiahome/domainname/130dftmail/unir.txt
