As far as I know, pretty much all hardware made in the last 20 years
ought to be able to do IPv6.  Slightly more recently, pretty much all
software ought to handle IPv5.

I think that what doesn't support IPv6 is many people and deployments.
I'm an example.

The ISP that routes my /24 doesn't support IPv6.  Not sure why.  They
must think that none of their clients need or want it.

I could use IPv6 because I have a second ISP (Rogers) that does
support IPv6.  But it seems easier to leave things as they are.  So
I'm a typical cause of the problem.

This would change in a flash if some site I cared about was IPv6-only.
Say Google or Red Hat.
