I just tried to set up an IPv6-only WiFi network at my house recently, and it was a total fail due to non-implementation of relatively new standards... starting with the fact that my Juniper SRX doesn't run a load new enough to include RDNSS information in RAs, and some of the devices I wanted to test with (Android tablets) won't do DHCPv6.

That’s a pretty old load then, as I’ve had RDNSS on my SRX-100 for several years now.

Only if you care about DNS.

An IPv6-only DNS server with RFC-1918 IPv4 connectivity to your XP box does solve the problem in question.

We're nowhere near ready for that.

Anyone who has that already has IPv4 addresses on all that ancient gear, so they can, in fact, dual stack at least that fraction of their network.

How about helping them deploy instead of continually trying to throw red herrings in their path.
