I read that comcast was using the "dual stack" CPE for /128 or /64 Ipv6.  I will be hooking my router to computers running Windows 7, Ubuntu 10.04, Droid OS's.  My new Netgear WNDR450 router comes with many selections for IPv6 connectivety.  Out of the choices below, which one would work with comcast?  I read on a forum that the "6to4 Tunnel" setting is what works best for Comcast connectivety.  I would like to get that confirmed.

 

Auto Detect - Router detects the IPv6 type.

6to4 Tunnel

Pass Through

Fixed

DHCP

PPPoE

Auto Config - If your Internet connection does not use PPPoE, DHCP, or fixed, but is IPv6.

It depends on your exact area and if you are included in the IPv6 trial.  If you are not in the specific area of California, or are using the business class service, then stick with IPv4 until such time as it does come to your area.  For example in my area (sourthern NH) no matter what IPv6 settings I set, nothing ever works, and both my cable modem and router both support IPv6.

 

So, unless it's being rolled out in your area, there is nothing for you to do besides watch and follow along.

They were running 6rd trials in certain areas a while back but I believe that these have now concluded.

My router is v6 ready but I am not sure about the sb5101 modem. During the test it passed as 6 to 4.

I am using IPv6 through a a 6to4 tunnel and it seems to work fine. Better, in fact, from my Linux machines than my Mac (I have no Windows to test with). My router is a Apple Airport Extreme and I've just changed the modem out to one that supports IPv6 in hopes that I'll get a real IPv6 range from Comcast some day. The 6to4 tunneling worked fine with the previous modem.

What games do you use that require IPv6 rather than normal IPv4?

No game I have every played online requires any such change and none of them require IPv6 since very few people actually have it at this point.  If you mean you need to change your IP address to get around an IP ban, that's an entirely different thing and has nothing to do with IPv6.  Perhaps you would care to explain things a little better?

Comcast started rolling out regular residential IPv6 this year.  It's going out slowly to different areas at a time.  The http://www.comcast6.net site is the best way to find out what's coming when.  I'd stay away from 6to4 though.  It works, but it doesn't necessarily work well.  You'll still use IPv4 in most every instance, except where a site is IPv6 only or you explicity connected to an IPv6 address.  Plus, it's technically a tunnel so you're adding latency to your connection and you can't gauranteee a return route.

Your best bet would be the IPv6 DHCP since Comcast plans on rolling out a native dual stack. http://blog.comcast.com/2011/11/ipv6-deployment-technology.html I'm in the same boat with my E4200v2.  In the meantime what I did was go to hurricane electric, got a free IPv6 tunnel and followed these instructions. http://www.tunnelbroker.net/forums/index.php?topic=1850.0 and it's been working for me under extremely heavy load. I get 10/10 on both IPv6 and IPv4 tests and I can connect to any IPv6 site without a problem. Ideally this is a stop gap measure until Comcast rolls out that native IPv6 of course.

No your SB5101 is not IPv6 supported as of yet, according to Comcast's page. http://mydeviceinfo.comcast.net/

One of the columns in the table of modems on that page is labeled "Pic." What is "Pic."?

"Pic" = picture. If a picture of a particular device is available there, click on it and you will see it.
