Comcast To Bring IPv6 To Residential US In 2010
darthcamaro writes "We all know that IPv4 address space is almost gone — but we also know that no major US carrier has yet migrated its consumer base, either. Comcast is now upping the ante a bit and has now said that they are seriously gearing up for IPv6 residential broadband deployment soon. 'Comcast plans to enter into broadband IPv6 technical trials later this year and into 2010,' Barry Tishgart, VP of Internet Services for Comcast said. 'Planning for general deployment is underway.'"
Verizon has IP6.

(I'm sure I read it somewhere around here).
Faster! Faster! Faster would be better!
Are you directly on Comcast or are you behind a router?
I have a WRT54G running Tomato and Comcast gives it a IPv4, and Tomato assigns IPv6 to my internal network.
There will be no paying extra for additional IPs. Everybody will get a /64. Look at this:
Addresses available in IPv4: 4,294,967,296
Addresses available PER CUSTOMER for IPv6: 18,446,744,073,709,551,616
This enables stateless autoconfiguration (usually based on MAC addresses) that simplifies everybody's lives.
There is alot more to IPv6 then just its IP Address space. there is lots of improvements to security, configuration, and multicasting. Also, the way it is designed will take a HUGE load off the core routers, and actually make them faster... Right now the address space is so fragmented, there are huge tables in them to parse on what subnets are down which paths...

If it was just a matter of software updates, but alas there are mountains of sites that are literally hard-coded to store IPv4 addresses and you get a nice PHP error when you attempt to visit them.
I guess I live a sheltered life, because I've been using IPv4 and IPv6 in parallel for about 7 years and I've never had a site break like that.
Dewey, what part of this looks like authorities should be involved?
That's because you are using an IPv6 address in the 6to4 address space, not a native IPv6 address.
And according to trace, your ISP doesn't have their own 6to4 router deployed, so the traffic gets sent to whoever announces the shortest route to 192.88.99.1 route via BGP.
(192.88.99.1 is a special IP which means 'any 6to4 router')

Because there's no such thing as IPv4 multicast... Oh, wait. That's exactly what cable companies have already been doing with switched digital. Multicast isn't the main reason a cable company would go with IPv6. The biggest problem Comcast (and other cable companies) has is that your cable modem gets two, and sometimes three IP addresses, let alone all those set-top boxes doing that switched digital. One to manage it, one to give you your "public" IP, and perhaps a third for your phone. 24 bits (10.0.0.0/8) only gives you 16 million addresses, and that's assuming you're utilizing them rather effectively. They're probably using the 172.16.0.0/12 for their internal network, but even so, that only gets you an extra million addresses. Look at the number of customers Comcast has, and you begin to see the problem they have just with addressing all those cable modems and set-top boxes.
Don't expect to be getting your own IPv6 address any time soon. Most likely, they're going to roll it out for managing all those devices first, and you'll still be assigned an IPv4 address for your Internet connectivity.
FWIW, I got their business-class internet and have been pretty happy with it. You pay a small premium over the consumer-oriented service (no 6 month introductory rate, and $17 / mo higher than the standard consumer rate), but they specifically told me there's no cap (and I haven't had any issues with that). Customer service is also separate from home users, which is great - short hold times, when I once had a problem, they sent someone out the next morning to fix it.

That's a link-local address. It doesn't do anything for you in the wider world.
That's because the line going to your house from the Telco is unique; it only goes to one place. It's the same reason you can add a jack for POTS and plug in any old phone and expect it to work.
Yes there is a fundamental difference. In DSL you have an individual line to the the phone company owned equipment (the DSLAM). Thus any data on that line is either data from you or data intended for you. On cable, your neighborhood shares a line. That is to say, that on the cable line that comes into your house is not only your data, but the data of the people next door (if they use the same cable internet service.) To prevent you from seeing the neigbors data, and to determine who sent anything in the other direction, the data is encoded (I would not dare call it encrpyted) with a modem specific identifier.

Err, I might be wrong. . . but while it's possible (may even be the default - if that's true, that's unfortunate) for your IPv6 address to use the Mac address as the last 48(?) or whatever bits of the IP address, I don't believe you *must* do that. I believe you can just use ::1, ::2, ::3, ::4, etc as the 'host' portion of the IPv6 address, can't you?
It's my understanding that IPv6 really doesn't care what the last 48 or 64 bits (I don't remember the exact number of bits for the host portion - just that it's a very large number of em) of the address is, so long as it's unique? I think the use of Mac addresses was just an 'easy' way to get a unique bitmask for that part of the IP address, isn't it?
