NetFixer posted : Add another D-Link router to the list of routers that seem to fully support Comcast's dual stack implementation. I've got to give D-Link a big thumbs up; they seem to be trying very hard to make their entire current residential/soho router product line IPv6 functional. Of course (as with most vendors) if you have an older hardware version that is not in current production, you will likely be out of luck unless your particular router is supported by OpenWRT, DDWRT, et al.

The D-Link US website does not have that firmware release, and it contains some significant improvements to IPv6 implementation over the 1.02NA firmware that is available on the D-Link US web site.

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).

NetFixer posted : 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.

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.

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]

NetDog posted : 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.

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.

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.

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.

Both directly connected to the cable modem (SB6121) and through the router (WNR2000v2). The computer is a Macbook Pro using Mountain Lion (10.8.2).

The router is set to "Auto-Detect" and seems to pass the ipv6 address to other devices just fine.

anon posted : I noticed yesterday that Comcast loaded a new firmware into my Comcast provided modem, and it does show IPv6 settings now, but they are not yet enabled. This is in Jacksonville FL with a business account and an SMC modem/router combination.

At the same time (probably) and the reason I checked the modem, my connectivity became pretty poor. The modem keeps getting very slow about every 1-2 minutes with pings to the modem itself exceeding 1sec. Also, the web based admin interface doesn't respond well at all. The modem is also not listed as IPv6 capable at »mydeviceinfo.comcast.net (but maybe they only consider the old firmware). I suspect they may be trying to do too much with this modem.

First, I am showing results using my WNR1000v2-VC again because something has changed and now it can connect to Comcast's native dual stack using "Auto Detect". Previously it had to be explicitly setup for "DHCP". Nothing on my end changed, the router still has the same firmware, but something changed. I am still getting the "/64" on the WAN instead of a "/128", but having to occasionally reboot it when the WAN IPv6 address changes is not as much of a PITA now that I only use this router as a guest router.

Next, are the results using my D-Link DIR655. The same notebook is used for this as was used above, I just changed which WiFi AP it associated with.

The WNDR3700v4 uses a newer Atheros chipset (as opposed to the Broadcom chipset of the v3, or older Atheros chipset of the v2) - thus, no third-party firmware is available (yet).
