You have promoted this discussion again and again over many years, yet 
you do not listen to any of the objections that people have.

You say this is not a new protocol, but you still specify a header 
format in section 4 of your draft.

You then state in section 5.2 that:

5. Advantages of IPv10.

     2) Allows IPv4 only hosts to exist and communicate with IPv6 only
        hosts even after the depletion of the IPv4 address space.

But this is an obvious lie.

What this "IPv10" allows, is for "IPv10" hosts to talk to other "IPv10" 
hosts if ALL of the routers on the internet between those two hosts also 
are "IPv10" enabled.

That is NOT the same as allowing IPv4 _only_ hosts to talk to IPv6 
_only_ hosts.  They both need to actively talk and understand this 
"IPv10" protocol and header format. You clearly do not grasp this, but 
this is the big issue with your draft.  You ARE suggesting that every 
single host on the internet should add another protocol to its stack, 
and you even believe that this can happen very fast:

     5) IPv10 support on "all" Internet connected hosts can be deployed
        in a very short time by technology companies developing OSs
        (for hosts and networking devices, and there will be no
        dependence on enterprise users and it is just a software
        development process in the NIC cards of all hosts to allow
        encapsulating both IPv4 and IPv6 in the same IP packet header.

While we are still struggling to get lots of devices to support IPv6, 
which has been in development and widely supported in operating systems 
and hardware for more than a decade.
So please. Until you understand what you are really trying to achieve 
here, do not expect any progress in getting this accepted by the 
community - and especially not the IPv6 community.
