That, like the 1897 report of Mark Twain's death, might be an exaggeration.

My company does testing of internet protocols.  Our customers include 
many, perhaps most, of the the "big names".

We *do* offer IPv6 products and we do run IPv6 inside our offices.

But demand from our customers for IPv6 is very light.  (Some of 'em are 
still trying to get IPv4 to work right. ;-)

We ask our customers whether they perceive IPv6 demand.

The answer is usually "no".

Between NATs letting a lot of air out of the need for addresses at the 
consumer end, and the fact that IPv6 doesn't solve the bigger (and 
harder) internet problem of routing, not to mention the klunky 
compatibility/conversion issues I'm perceiving IPv6 as the Little Engine 
that Could - we hear a lot of "I think I can, I think I can" - but we 
don't yet know whether it will actually make it to the top of the hill.

By-the-way, and definitely less seriously, there are "stories" about 
some of the predictions of IPv4 exhaustion - mine, from 1990, is here:
