When we were running AppleTalk and IPX not many of us had corporate access to the internet. I remember those IPX days, and one of the driving reasons to move to IP was to get internet access. I remember adding IP to our Netware 4.x servers. Because IPv4 is the lingua franca of the internet, I don't think we can directly compare it to AppleTalk and IPX.

How many 10 year old pieces of kit do you have on your network? Ten years ago we were routing appletalk and IPX. Still doing that now? Ten years ago companies were still selling ISDN routers which still insisted on classful addressing. Got any of them left on the network? I'd expect that v4 will still exist in legacy form behind firewalls, but I think its deprecation on the public internet will happen a lot faster than anyone expects.
I agree that v6 deployments seem to be getting better/faster/stronger... I think that's good news, but we'll still be paying the v4 piper for a while.
Only until v4 becomes more expensive (using whatever metric matters to you) than v6. After you pass that tipping point, v4 deployment will stop dead. - mark -- Mark Newton Email: newton@internode.com.au (W) Network Engineer Email: newton@atdot.dotat.org (H) Internode Pty Ltd Desk: +61-8-82282999 "Network Man" - Anagram of "Mark Newton" Mobile: +61-416-202-223
