The new normal????

The IPv6 Internet is a different network, a separate Internet, from the
IPv4 Internet which everyone uses.  Email is the only application which
works transparently between them.  Nothing else is directly
interoperable, since they are different networks, with different address
spaces.  An connection to the IPv4 Internet cannot be used to send or
receive packets to or from a connection to the IPv6 Internet.

IPv6 has supposedly been ready to go since RFC 2460 of December 1998, so
it is 13 years old already.  It hasn't been adopted at a great rate
since then.

No matter how desirable it would be for IPv6 or any other approach to be
a seamlessly backwards compatible upgrade from IPv4, no such thing
exists.  No amount of talking up the difficulties of exhaustion of
previously unused IPv4 address space (its not really IPv4 address space
exhaustion), and no amount of wishful thinking "it becomes the new
normal for the Internet" will change this.

There is, for all practical purposes, for ordinary users (who need to be
able to communicate with the hosts of all other users) one Internet -
the IPv4 Internet.  To talk of these two networks as if they are both
part of one Internet is misleading.
