Hello Al,

It will not be THE determining factor, and IPv4 will never completely disappear just as IPX has not disapeared completely yet. But there will come a time when IPv4 can no longer be used to connect systems across the Internet. It takes cost and effort to support a dual stack environment and in the foreseeable futute someone will come to the conclusion that the benefits of maintaining IPv4 will no longer justify the cost. And that will be the start of the end of IPv4. I expect to see this in the coming decade. Tough luck for those that still use IPv4 only stuff. But h‚ IPv6 had been around for a while, and those that have still been buying IPv4 only stuff for the last five years have only themselves to blame. Forunately WinPoint now supports IPv6, so Winpoint users have nothing to fear. 

Cheers, Michiel
