Waiting till IPv4 is turned off globally is way too long. You want to be ready for the first IPv6-only site that you want to communicate with, or which wants to communicate with you. It may be very soon, or possibly have already happened - I don't know if people trying to send me mail have failed due to my mail server not yet supporting IPv6. If you're exclusively doing client-side stuff, then I guess at least you'll be the first to know when something doesn't work :-) Is that when you want to be turning it on and figuring out any issues? > It really comes down to the cost/benefit ratio.

Fair enough. Maybe :-) I don't claim to understand all of either IPv4 or IPv6 either. And most of my learning has been due to some requirement. But it's been a long time since I deliberately turned IPv6 off (IIRC); if something doesn't work, that's something to learn about, not to disable, if I can help it. Richard
