Ars Technica on IPv4 exhaustion

"IPv6 will never become the defacto standard until the vast majority of
users have access to IPv6 connectivity."

It may never become the defacto standard, period. Nearly 20 years to reach
2% penetration is a strong hint that the costs outweigh the benefits.

IP's global addressing system is broken from the outset. See John Day's
presentation "Surviving Networking’s Dark Ages - or How in the Hell Do You
Lose a Layer!?"
<> (or,
indeed, lots of them at once.)

It's really all about scopes, not layers - the TCP/IP architecture is
divided up the wrong way, and it will never be fixed. It's an escaped 1970s
lab experiment that was able to extract the statistical multiplexing gain
faster than rivals, but on a performance and security "buy now, pay later"

If you want to see a viable alternative approach, read my post "Network
architecture research: TCP/IP vs RINA"
<> for an
introduction. That said, I'm not expecting anyone to immediately resign
their membership of the Seven Layer Adventists as a result. Yes, the
Internet's intellectual foundations are rotten - but that is too much
anxiety and dissonance for most people to cope with.

May all your intentional semantics become operational,
