I agree that the RA stuff works fine - the problem is getting DDNS to work. Many people currently drive DDNS updates from their DHCP server.

I think that more tightly controlled sites can experiment with that - but how should vendors of home routers support IPv6, for example? Currently, if you take a default install of OpenWRT on a router, it can provide a convenient DHCP + DDNS experience for IPv4 that "just works" with no setup required. I'm yet to see that the same "plug and play" experience is possible with IPv6 - I agree it is possible in theory, but I'm not sure about the way it people have been implementing it. > > One issue I've observed on older machines that have been upgraded is > > that the IPv6 setting in NetworkManager is sometimes set to "Ignored" > > while on fresh installs it is in "Automatic" mode - so people who have > > upgraded need to go in and change that or they won't experience dual > > stack. > > I can believe it. > On my new laptop, I tried NM again, and it has a habit of opening a hundred > WPA passphrase requests :-) We have a laptop at home near the edge of the wifi zone that regularly gets into that state - if nobody uses it for a few days, there are 1,000 popups open -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
