Furthermore, he stated that networking equipment companies like Cisco will be moving away from IPv4 in 5 years or so. This is the first time I've heard this posited -- I had a hard believing that, but he claims it with some authority. Anyone hear anything like this? My own opinion is that we'll see dual-stack for at least a decade or two to come.
ISP's are very good at one thing, driving out unnecessary cost. Running dual stack increases cost. While I'm not sure about the 5 year part, I'm sure ISP's will move to disable IPv4 support as soon as the market will let them as a cost saving measure. Runing for "decades" dual stacked does not make a lot of economic sense for all involved. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
