Re: [IPv6] Evidence of Comcast IPv6 CPE Dual Stack (CPE and CPEP Union City, CA (SF East Bay)
Power cycled my Motorola SB6141 today and noticed that a new SW INIT log entry started.
New firmware SB_KOMODO-1.0.6.10-SCM00-NOSH (up from the previous 1.0.6.8).
Also, under the "Configuration" page, the DOCSIS MIMO now reads "Honor MDD IP Mode" while Modem's IP Mode now reads "IPv6 Only". Both of these values previously related to IPv4 only. |

1 recommendation | The DOCSIS MIMO or MDD IP Mode is for the cable modem management interface only. That doesn't have anything to do with your side (CPE side) of the cable modem. |

1 recommendation | Thanks for clearing that up!
So what is the big deal about it then if it's not CPE relevant? |

Because it is relevant to the MSO, we need to know what mode your cable modem is reporting. So not relevant to the user, just the MSO. |

FWIW, you are not currently using Comcast's native dual stack; you are using a 6to4 tunnel. Try the test at »test-ipv6.com/ to see details (this is the test that Comcast based their test on, but Comcast has not updated their copy of the code to provide the additional information that the current test provides).
A ray of hope is that possibly your new router might be able to utilize Comcast's native dual stack since Windows XP's IPv6 implementation doesn't natively support DHCPv6 and that may be why you are currently using a 6to4 tunnel.

User NetFixer is correct Windows XP doesn't support DHCPv6 so a tunnel would be the only thing you get. But this is why a Windows XP device will work behind a router, your router will send the RA to the XP box and tell it what to do.
Bottom line Comcast only supports DHCPv6\DHCPv6-PD on the WAN side of your modem.

Looks like dual stack is working here but I'm getting a message about it appearing I have a non-managed tunnel configuration because they are showing 2 different ASNs.

Since you have IPv6, we are including a tab that shows how well you can reach other IPv6 sites. [more info]
It appears that you use a non managed tunnel mechanism for either IPv4 or IPv6. [more info]
Good news! Your current configuration will continue to work as web sites enable IPv6. [more info]

1 edit | This new behavior by »test-ipv6.com does not indicate a problem with your dual stack IPv6 connection. They have always tried to detect if you are using a tunnel (and they used to do it successfully), but their current AS number comparison test needs some tweaking on their end.
If you go to »as.robtex.com/as7922.html and »as.robtex.com/as33652.html you can see that AS7922 feeds AS33652. This apparently is confusing the »test-ipv6.com tunnel test. An additional routing step != a tunnel.

There is nothing that says that IPv4 and IPv6 traffic to/from the same device/network has to take the same physical path. I separate public IPv4 and IPv6 traffic for both of my dual NIC servers (except for DNS traffic to DynDNS which I always make sure goes through the same registered gateway).
