Re: [IPv6] Evidence of Comcast IPv6 CPE Dual Stack (CPE and CPEP

jjgregory See Profile a 2002 means you are using a 6 to 4 tunnel rather than a native IPv6 so you aren't quite done.
As you point out That router doesn't have IPv6 support, but I believe openwrt, dd-wrt and shibby all firmwares can help
as always at your own risk

Marietta is a suburb of Hotlanta.
Win 7/64 bit with an E3000 Router (which is not IPv6 compatible).
Using a Cisco SG-200-08 Managed Switch behind the Router with IPv6 and LACP Teaming enabled on a 2GB Home network.
All the IPv6 addressing that one would expect to see in the Network Connection Details is there.

Got native ipv6 south of Covington, WA. Using Toastman Tomato with IPv6 mode set to "DHCPv6 with Prefix Delegation".

I actually was having problems accessing some sites this morning (especially Google ones) because my router was configured to use a tunnel or whatever while my router was getting a native ipv6 address. Seems to be fine now that I've switched over to DHCPv6 w/PD and removed all static address stuff.

Re: [IPv6] Evidence of Comcast IPv6 CPE Dual Stack (CPE and CPEP

said by MDA:

Router is set in Pass-Through mode because prefix delegation works on Comcast's end (no need for DHCPv6 since DNS addresses and other client IP's passthrough successfully).

I'm not too worried ill reach the 18 quintillion address limit either

That is not the correct setup.. You shouldn't use pass-through, we will only issue you as many IP's as your account allows. You should have your router setup to accept a PD. This way all your devices will get a IP from the Pd scope and not the WAN scope.

Your IPv4 address on the public Internet appears to be 75
(COMCAST-22258 - Comcast Cable Communications Holdings, Inc)

Your IPv6 address on the public Internet appears to be 2601
(COMCAST-7922 - Comcast Cable Communications, Inc.)

Since you have IPv6, we are including a tab that shows how well you can reach other IPv6 sites. [more info]

Good news! Your current configuration will continue to work as web sites enable IPv6.

Rediness score: 10/10

Keep up with the good upgrades, NetDog. Your IPv6 upgrades have spread to Louisiana and the Cisco 10k CMTSs that we have here!

Now packets from my LAN aren't even making it to hop 3 in the traceroute I posted. PMs sent.

I did have an issue a couple times where OpenWRT's new DHCPv6 client (odhcp6c) freaked out and started sending packets out the WAN interface as fast as it could (many thousands per second), using 100% CPU. This happened once a couple months ago and again a few days ago, which was why I decided to update OpenWRT Tuesday night. I didn't really have a chance to investigate since at the time I just needed my router to stop being slow (killing the process fixed it). I'd been wondering if that would cause me to be IPv6-blacklisted or something. But hopefully since IPv6 wasn't enabled then (at least the first time) the packets never made it to the DOCSIS side of my modem...

Can you run your tests again? Your CMTS wasn't properly advertising its IPV6 routes, we corrected the config and you should be good now.

Actually it appears that my router is working, and Comcast just hasn't finished enabling IPv6 here yet.

My router itself has full IPv6 connectivity, but machines on my LAN can't reach the Internet. At first I assumed my router wasn't routing, but traceroute6 says otherwise. On the router:

Clearly packets from my LAN *are* making it out of my router into Comcast's network (the 2001:558 addresses), but Comcast is not routing packets to and/or from my LAN.

It's interesting how they do this in stages: last night my router wasn't getting any DHCPv6 responses, but it was spewing messages about being unable to reach several addresses in 2001:558:4082:63::/64. I assume it was receiving ICMPv6 packets and trying to respond, but couldn't because it didn't have an IPv6 address (?).

Oh well, I'm patient. :-)

Looks like they're in the midst of enabling it here. comcast6.net says my CMTS is supported. test-ipv6.com says I have nothing, but machines on my LAN have an IP...or several...

Very possible that my router is misconfigured or buggy (OpenWRT trunk from last night, with some old config files that probably need to be updated). I'm looking into it.

Re: [IPv6] Evidence of Comcast IPv6 CPE Dual Stack (CPE and CPEP

Congratulations! You appear to have both IPv4 and IPv6 internet working. If a publisher publishes to IPv6, your browser will connect using IPv6. Your browser prefers IPv6 over IPv4 when given the choice (this is the expected outcome).

Your DNS server (possibly run by your ISP) appears to have IPv6 internet access.

I hadn't noticed this until today. The modem has been at IPv4 for I don't know how long. I've been troubleshooting a network problem and the IPv6 popped up on the modem status page.

Edit: It would seem that the Netgear WGR614v10 does not support IPv6. Wonderful!
