        Isn't IPv4 a subset of IPv6? So it shouldn't matter if my home router or modem is compatible, if the changeover is done properly. My ISP would do the equivalent of NAT routing with my IPv4 address being part of the IPv6 address the ISP sends out to the world.

          Nope - IPv6 and IPv4 are essentially two similar, but distinct, protocols. This is why the transition is not a trivial thing to do.

          Dan is correct, at layer 2 the 802.3 frames are compatible but at layer 3 the packets are not compatible. Things like switches will generally pass IPv6 traffic with little or no trouble but routers and firewalls will ignore IPv6 traffic unless it support (and is configured for) IPv6.

          Very roughly speaking, none.

          If you want to experiment with IPv6, I strongly recommend that you get yourself a router supported by OpenWRT [openwrt.org] and reflash it. This will also give you the ability to do all sorts of things that consumer routers usually don't do, such as traffic shaping [wikipedia.org], arbitrary subnetting, dynamic routing, or simply basic router functionality with fewer bugs.

      Assuming you go the anycast route (since that's what Comcast being ready for IPv6 would imply), once your router is configured properly your systems should autoconfigure themselves with globally routable IPv6 addresses starting with 2002.

        I think it's a matter of Cogent trying to strongarm its position. It wouldn't be the first time Cogent has done this and it certainly won't be the last. Doing a Google search for "peering dispute", and not including Comcast (to exclude the Comcast vs. Level3 dispute since it's newer and ongoing), almost every old entry involves Cogent duking it out with someone. They win customers on price, but things seem to be lopsided enough that they get into a scuffle with a number of the other Tier-1 providers.

      The test is aimed squarely at you.

      What stops the large content providers from serving over IPv6 right now today is a level of brokenness that affects a fraction of a percent of users. These are computers or networks which are nominally IPv4 only, but have some misconfigured IPv6 setup that is actively causing problems connecting to sites. The proportion of users is tiny, but if you're facebook, that's still a lot of users. Wednesday next will expose these problems on a temporary, scheduled basis.
