Dear Borg: 1) " ... I dont see a way of extending IPv4 without making it a new protocol. ... new IP protocol that is much more similar to IPv4, just extends address space. ... ": I believe that you will be pleasantly surprised at the proposal summarized by the the below whitepaper. It proposes an overlay architecture over the current Internet. As such, assignable IPv4 addresses are extended without the baggage of the current Internet and no new protocol. To begin the deployment, all need be done is "*/disabling/* the program code that has been */disabling/* the use of the 240/4 netblock" in routers. https://www.avinta.com/phoenix-1/home/RevampTheInternet.pdf 2) The "transition" will be mostly transparent from ordinary users' point of view, because IoTs do not need be reprogrammed. Please feel free to ask me to describe specific issues that you may come across.

From my knowledge I dont see a way of extending IPv4 without making it a new protocol. It was not designed that way.
What I would LOVE to see that someone will pop in with new IP protocol that is much more similar to IPv4, just extends address space and fixes some well know issues. (for example remove netmask and use prefixlen/CIDR). Other importand aspect is some kind of IPvX -> IPv4 interop, so you can quickly put clients into new protocol and they have access to entire IPv4 internet out of the box. Also, we need to please enterprises so we need largish RFC1918 space too.

Its not impossible to envision that IPv4 does not ever go away but actually gets extended in such a way that it obsoletes IPv6. The longer this drags out the less implausible it seems.
