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

Oddly, I no longer have an IPv6 address. Had it a few days ago. Not sure why it disappeared.

Edit: Now suddenly it is back. Weird.

Still nothing here (Cape Cod Mass). The head end has not been upgraded for IPv6, and although modem seeks ipv6 address from Comcast on ip4 gotten.

No word at all.....

Noticed my ASUS RT-N66U picked up a IPv6 address this week in North Branford, CT (Branford, CT system). Looks like I'm part of the future now! Everything checked out on the readiness page.

Thanks! After it came back up, I still have an IPv4 address, no change.

In CT here. Internet has been down about an hour. Looking at the modem log I am seeing a ton of entries that state: Honoring MDD; IP Provisioning Mode =IPv6. Assuming that we are in the process of being upgraded. The tech support person I talked to said it is a planned outage.

I point to and quote..

#1 »[Internet] Buffalo, NY area CMTS now emitting IPv6 RAs

quote:
EDIT: One thing I had been wondering, and is finally answered: Does ipv6 depend on seeing ipv6 on the Motorola (SB6120) configuration page? No, it does not. "IPv4 Only" mode must mean for managing the modem itself, not what's attached to it.

#2 »Re: [Internet] IPv6 just appeared on my connection

quote:
The modem IP mode listed is for the management of the modem, not the end user IP.

#3 »[IPv6] Modem's IP Mode: IPv6 Only

quote:
The Modem IP Mode on the web interface only refers to the management side of the modem, but it means your CMTS is IPv6-enabled, so you are likely dual stack.

#4 »[IPv6] I'm a bit confused about IP6 and it's relation to me ....

quote:
Your cable modem has an additional IPv6 management interface address, that's all. It has no meaning to you or your network. Just ignore it.

If you want to use IPv6 as well as IPv4 on your network, that's another story. You will need to be in an area that has IPv6 service, and you will need an IPv6 compatible modem, router, and operating system on your PC.

ETC..

Shoot...That stinks.....Well, we both waited a long time for it to finally show up in our area, so I guess a little longer won't hurt. It's worth the wait. When my modem reset early yesterday morning I thought it was a speed upgrade (wishful thinking but it may have been acquiring the ipv6 address. At least I suspect that was the reason it rebooted.

Hey there Plat...Yes, you're correct about the same CMTS. Comcast6.net also gave me this message:

Your IP address is 2601:6:4b00:a4b:cd4e:970d:2015:a995
Congrats! You are using IPv6 on the Comcast Cable network.

Looks like I am good to go. Glad were on Native/Dual Stack IPv6. Now.....Nirvana would be to have our speeds doubled again. Otherwise I am a happy camper!

I guess we aren't on the same CMTS, I still have no IPV6

Your IP address is 76.127.x.x
Your CMTS is not supported at this time.

I am running Firefox v.28 and I checked the "about.config" settings for IPV6 and the value is set as false which it should be. Anyway, just glad to get rid the HE tunnel and have what appears to native IPV6. Thanks Netdog for your hardwork.

Realized my screen capture looked a little different than anybody else's because I was using the wrong site, sorry about that, added the right one.

Actually, »test-ipv6.com is a better test site, and offers helpful diagnostic infomation; and it is offered as a test link on Comcast's »www.comcast6.net site as an alternative to their own customized three year old copy of the same code (notice the "World IPv6 day is June 8th, 2011" statement on Comcast's version of the test).

Modem: DBC2100R2
Router: None, directly connected to modem from Linux (Ubuntu 12.04 Precise)

I've been running a cron job for a while which automatically checked »www.comcast6.net/ for IPv6 availability, and it just became available today.

My modem is *not* listed as supported, so I'm surprised this has worked at all.

I have been trying all day to get it to work with my WAP between my computer and my modem, unsuccessfully. My WAP is a TP-Link TL-WDR3600. I've been able to get a v6 subnet delegated, reboot my workstation, and get a global v6 address there, but then get nothing but "network unreachable" when attempting to connect to anything (with the WAP hooked up, as I said, it works when connected directly).

I am curious if my problems are caused by the fact that I'm using a modem that is not listed as supported.

Cron job which I used to find out IPv6 became available:

27 4 * * * links -dump »www.comcast6.net/ | grep 'Your CMTS is not supported at this time' || echo '»www.comcast6.net/' | mail -s "Comcast may have started providing IPv6" youraddress@example.com 2> /dev/null

(Please use a random time, so everyone isn't hitting it at once.)

Not really sure why my browser is preferring v4 over v6, sorry about that.

Edit: Fixed the warning about my browser preferring v4 over v6 by disabling network.http.fast-fallback-to-IPv4 under about:config in firefox.

Edit: Realized my screen capture looked a little different than anybody else's because I was using the wrong site, sorry about that, added the right one.
