Hi Tom.
Regarding this statement: "this can be accomplished by technology
companies in a short time" -- I see no technical basis for this
claim.
The technical basis is to allow encapsulation of both versions in the
same L3 packet header.
Well, there are multiple ways to encapsulate versions of IP in a same
packet header.
One is to use IP-in-IP encapsulation. You could do IPvx-in-IPv6.
Another is to multiplex with a number below IP. For example, you have
an EtherType for IPv4 and another EtherType for IPv6. The EtherType
field is in an Ethernet header which is below IP. You could see
EtherType quickly if you download the free tool 'wireshark'. You dont
have to be a software developper to do that. Architects use wireshark
extensively.
Another one is to use an IPv6 Extension Header called "Routing Header".
You could put an IPv4 destination address _and_ an IPv6 destination
address in the same Routing Header. As a result, the packet would be
travelling to IPv4 Computers and to IPv6 Computers too.
That said, I agree with you that that the technical basis is to allow
encapsulate versions of IP in a same packet header.
I would also rather say: the technical issue is how to use different
versions of IP in a same IP packet.
Since the initial posting of the IPv10, I and and others have asked
several times for an implementation.
Yes, this have to be tested because theoretically it works fine
I agree with you. Many concepts are first imagined in someone's mind,
then sketched with a pencil on a paper, and discussed. These concepts
work fine theoretically.
and I'm not a software developer to test it by myself.
You are not. But can you make their job easy?
Me too I can sketch a concept car on paper, but I doubt any manufacturer
will ever make one :-) Because I dont know how to make cars.
