V6 still not supported

What you describe is literally IPv6.

If it is so easy, then why is some software not yet supporting IPv6? What makes you think that lazy software developers would suddenly become interested in this new IP when they don't seem interested in the current standard?

I don't get what you are trying to accomplish here that is not already covered by IPv6.

No, it wouldn't. You have a fundamental misunderstanding about how IP addresses work. Nothing stores IP addresses in the classic (and horrible) IPv4-style dotted notation. IPs are stored as binary numbers, be they 32-bit, or 128-bit. The way they are displayed are just a shorthand to make reading them easier (although, the variable character length of IPv4 is really annoying, but is fixed in IPv6)

Again, you are basically talking about IPv6. I am still missing where you have some way to accomplish the same goal without having every system have to be re-written (again). Why would we want to start again at 0% when we are a significant portion of the way to full IPv6 deployment?

As others have said, this has been fixed. I do agree that leaving out DHCP was shortsighted. But it was relatively easily added (just like it was for IPv4). Just because the current implementation and best practice for a protocol doesn't meet a specific need of yours doesn't mean we should go back to the drawing board and re-implement the entire networking stack again.

As above, I will point out that you seem to have a misunderstanding of what IPv6 is and is not. Hex vs. dotted quad is merely a display standard having nothing to do with anything that really matters (router code, etc). What you seem to be proposing is just a different way to represent 128-bit addresses, which would make them difficult to distinguish from 32-bit addresses. These issues have long been worked out by many very smart people.
