You seem to be focused on nodes outside of the Internet, as opposed to the infrastructure that creates what most people view as "the Internet". From a user's point-of-view, the edge of the global, public, 32-bit, IPv4++ Internet is defined as the collection of private companies and people, connected together, that pass 160-bit headers with the **8-bit TOS field unchanged**. Those 8-bits can be used to expand the addressing at the edges of that network, 4-bits are needed in each direction. That expands the address space by adding 15 more Internets, as large as the legacy net. That creates yet another layer or edge, composed of equipment that combines to make people see 4 extended address bits, for a total of 36. You can easily obtain code to do this, or help write more code to do it. http://www.netfilter.org/ http://netfilter.samba.org http://www.google.com/search?q=TOS+routing http://www.google.com/search?q=packet+mangling As for IPv6, one can not assume that the 128-bit DNS implies IPv6. As an example, if you use a 2002 model year address, such as 2002:[IPv4]:* in the 128-bit DNS AAAA records, your computer will likely generate IPv4 packet headers. A6 DNS records are for IPv6. AAAA records work for IPv4++. Private companies and private individuals are working together to define what goes in the AAAA records. You are FREE to participate. Some private companies and closed societies may try to tell you that you are not free to participate, but that is not the case. Even with tens of millions of dollars from domain name sales and address space leasing, they will not be able to pull together enough money to buy the freedom of all people on planet Earth. They may try...but, most people's minds are not for sale.
