You can request a fully working IPv6 implementation, but it's not going to stop a purchasing if it doesn't. If you 
are deciding between two vendors and one is better/cheaper and doesn't have IPv6 and you choose the other, it's 
likely you will be looking for another job. There is no strong justification for deploying IPv6 in a corporate 
enterprise currently. Corporate world is focused on the next quarter, not at a 10 year horizon.


Which is it? You need equipment that's right for the next 5-7 years, or, you need to focus on next quarter and not a 
"10 year horizon"?

We decided to  roll it out for a number of reasons. One, we had time this summer. Two, we figured it would highlight 
inherent issues already in our environment (it did, and we found a few doozies), and finally it was a good 
intellectual exercise. We have it running on all over our desktops, and most of our servers (some issues with license 
management software and other legacy software prevents us from deploying it on all servers)

This seems wise. Hopefully you're working with your vendors on getting those issues resolved.

If we had an orderly shutdown of our IPv6 environment, there would be zero impact to the business. In fact, due to 
complexity issues, it would arguably we would arguably be better off without it. Perhaps in a few years things will 
be different. My bet is that even in 5 years, corporate adoption will be very small, maybe as low as 10%.

Maybe... However, what do you plan to do when your employees don't have IPv4 connectivity at home any more? That's 
likely going to either go away or get a lot more expensive in about 5-7 years.  That's not just my prediction... Lee 
Howard has some pretty good information to back it up. Check out his presentation from the Denver Inet in April of this 
year.

I don't know that this is a practical option... for say some systems I
know that don't do v6 properly or at all, and which have buying cycles
on the 10yr horizon, not 2yrs/etc.

And I hate to say it but people have been saying for over a decade.

     * request support IPv6 in the products you are purchasing.
     * test the IPv6 support.
     * report the bugs found so they can be fixed.

This situation was foreseen.  Too many people just left this for
later and later is here now and the fixes will come too late for
some.

BUT... so what? you can do v4/v6 on the same LAN, right? just only use
the v4 bits for those devices?

I don't think 'eh, toss out your crap, buy new crap' is the right
message to send. 'you can cohabitate, this isn't virginia' is though.
