Re: This just in.....IETF announces IPv7
Not a separate protocol for starters. At the moment, you have the choice of IPv6, IPv4 or both. Imagine if IPv6 included IPv4 functionality, such that OS vendors etc. could drop IPv4 as a separate protocol. It would have helped drive IPv6 adoption as you'd have to enable it to get connectivity. Not saying it is a perfect solution, but the current situation is that IPv6 is too easy to just disable/ignore.
