Google, Facebook and another large website is doing a big switch to IP V6
here soon (for one day). Apparently it is possible, but I would hire some
sort of expert to make sure that you do it right. I would say internally,
unless you have some requirement that you aren't saying, stick with IP V4.

We are getting ready to move down the road a few miles, to the next
city. Anyhow I was thinking of changing to IP V6 at that time. We are
purchasing new routers and switches for the move. They should all
handle IP V6. Our iSeries are at V5R4 and V6R1. Our windows domain is

firewall have to NAT IP V4 to V6?

Is it worth it? Oh and our in house programs will not support the V6
addressing at this time.

file that I use for Lotus Smart Upgrade was causing me grief. In
7 (to enable IPv6) they replaced the output of IPCONFIG from IP Address
IPv4 Address. Piping using output is never as good as APIs (as I found
out a decade or more on the i).

We also have one lpar feeding our DMZ. Actually using the DNS on the i
and all. I suspect that one will get hit by IP6 at some time. But our
network admin generally agrees that internally IPv4 should be
