IPv6 Support

Wondering the same thing. Comcast has native dual-stack in my area but I'll be moving in 2 months to TWC-ville.

From the Time Warner website - "Subscribers of our wideband tier, and Signature Home customers, will automatically have IPv6 enabled when it is available in their area. Subscribers who provide their own home gateways should look for gateways supporting IPv6."

Which suggests that Time Warner will support IPv6 when THEY are ready to do so, which may not coincide with when customers believe themselves to be ready.

So how do you know when you've got a valid IPv6 address?

I'm getting this on my router:

fe80::200:24ff:fecb:53cc%vr0/64

Or visit this site -

test-ipv6.com

which will tell you what your IPv6 address is if you have one

When your network adapter status looks like my screenshot

My bad then. It should look the same, you can always go to the test site the previous poster shared or if you have a router that has an IPv6 section it'll show it. My netgear has an easy to read area that tells me if the WAN port has one or not.

In my area, TWC's network is AS20001. According to »bgp.he.net/AS20001, its IPv6 prefixes are 2600:5c00::/32 and 2605:e000::/32. So I'd expect my IPv6 assignment to be in those subnets (unless of course they are assigned more before they do the roll-out).

But still no sign of it here (LA), using an Apple Airport Extreme. I would expect it to be quite a few months before they finish rolling it out over their entire footprint.

That screen doesn't prove anything. It will show "internet" as long as any IPv6 system is working (teredo, 6to4, isatap, external tunnel.) Show the ACTUAL addresses being used.

It was only online for a few hours the afternoon of world IPv6 day or I would have more to show. Since then it says the typical "No Internet Connection" next to IPv6, also only IPv6 address listed when I view the details is the one local on my home network.

Another way to check v6 connectivity: traceroute to ipv6.google.com or similar. If it resolves, you're golden. If not, you're v4-only.

When I get TWC in Austin I'll be sure to grab a v6-capable router (I think I'll bring my v6-capable SB6120 down if they'll let me use it on their network). I mean, might as well...

The 6120 is not a compliant customer owned modem at this time.

Sent an inquiry to the main support for Bright House, and got a reply:

Thank you for taking the time to contact Bright House regarding our IPv6. We do have the IPv6 available. What we would suggest is to contact our Internet department and one of our agents will be able to check and see if you are on the IPv6 or when it will be available for you.

Everything in the fe80::/16 range (not sure about the size, I think it's /16) is "link local". That means that address is only usable on that network segment; it should not/will not traverse the Internet. Most publicly routable IP addresses start with 2. For example, both my Hurricane Electric tunnelled addresses and Google Public DNS use addresses starting with 2001 (which is cool for me, I like to add "an Internet odyssey"). I've also seen addresses expressed starting with 2600:.

I would look at your cable modem. For example, on Motorolas, there is a "mini Web server" at 192.168.100.1, and that has a configuration page; one of its items reads "IPv4 only" for "Modem's IP Mode".

Jeopardy! replies and randomcaps REALLY suck!

Are you saying that if I have an SB6120 I will never get native IPv6 addresses (unless policy changes of course)? Are you additionally saying that if I get/"start renting" * a CM from TWC I will get native addressing?

Side note, and I just want to emphasize, admittedly totally MY fault: The only reason I dumped using the SB5100 I had for years, and went and purchased an SB6120 was for the D3 compliance, and that for the IPv6 capability. At this point it's just for my edification, whether I wasted my money or not.

* Just to explain why that's in quotes: during the Adelphia times and most of the time to date during the TWC times, a company-provided cable modem was a line item on monthly bills. Then a few years ago, in the program I'm grandfathered into, the final amount was the same, but it was itemed instead as a "customer owned modem credit" of the same amount ($3)...which means technically I wouldn't be renting the modem because it's supposed to be part-and-parcel of the Internet service.

I am saying that the 6120 is not on a list of customer approved modems. If it supports IPV6 I am sure it will when its rolled out.

I think all this IPv6 stuff is nothing but false advertising. I asked Roadrunner on the forums here if it was available in my area, and got this reply.

"Sorry, we do not know when it IPV6 will be available to our residential customers at this time."

Apparently its only for business customers, as if they would be the only ones who would use it.
