Big difference between Joe Sixpack and Joe IPV6-pack. 2) Even if some Joe Sixpacks manage to get into the test, that's good - because Comcast needs to know what the unclued masses need for support, etc. pgp2N2EDXmtvD.pgp Description: PGP signature

That really makes sense - on an incredibly smaller scale (and I mean MUCH smaller scale), we operate cable modem in two small communities - currently we use 3 IP addresses per subscriber. One for the cable modem itself, one for the subscriber (or more depending on their package), and one for voice delivery (packetcable).

Other providers are moving in that direction, atleast a couple are (as a swag) 6-18 months behind Comcast ... /TJ I have no particular reason to to doubt that claim, and lots of reasons to actively hope that you are right. That said, the appearance of more public commitments like this -- and sooner rather than later -- could make a large difference, e.g., by reducing the general level of uncertainty (and uncertainty-amplifying speculation) during the terminal stages of IPv4 allocation. While no commercial entity would (and none should) willingly make such a public commitment before they're ready, it would be prudent to consider the potential downsides of that looming uncertainty when making judgements about how ready (or perhaps ready enough) should be defined. Might be worth noting that Comcast has been using IPv6 heavily for internal connectivity (including router access) for some time and already had substantial experience with IPv6, so I suspect that they are ahead of others on this. -- R.

Re: Comcast IPv6 Trials
Typically the CPE address is private, not sure why they would use a public IP. The MTA (VoIP) part of the modem would need a public IP if it was talking to a SIP server that was not on the same network. Most smaller cable system outsource their VoIP to a reseller with a softswitch.

If we moved even two of three IP assignments to native V6 we'd reclaim a lot of V4 space - I can only imagine someone their size and what this means... Paul Excuse the newbie question: Why use public IP space for local CPE management and VoIP? Doesn't DOCSIS support traffic separation? /J

Re: Comcast IPv6 Trials
Wonderful! In all seriousness, will any attempt be made to select trial applicants based on (apparent) clue level and/or to receive feedback through channels other than the usual Tier 1 support?

From http://www.comcast6.net/faq.php: *How will you select trial areas?* Some of our trials will not be geographically-bound, meaning a customer from anywhere in our network could participate, while other trials will be bound to particular areas. *How will you select customers to participate in these trials?* Customers can volunteer to participate in a trial by completing an online form at the Comcast IPv6 Information Center, at http://www.comcast6.net/volunteer.php. Once we're ready to start a trial, we will search for customers meeting any applicable criteria for participation (geographic area, home computer OS or equipment, etc.) and invite them to participate in a specific trial. I'm excited to be on the same side as the 500lb gorilla for once, -Nick

Thanks. Initially it would be ideal (even preferred) to target trial subscribers with greater IPv6 awareness. The technical team will absolutely remain engaged as part of the support process.

Without going too far, what was the driving factor/selling point to moving towards this trial? SWAG: Comcast is a mobile operator. At some point NAT becomes very expensive for mobile devices and it makes sense to use IPv6 where you don't need to do NAT. Once you deploy v6 on your mobile net, it is to your advantage to have the stuff your mobile devices connect to also be v6. Do do THAT your network needs to transport v6 and once your net is ipv6 enabled, there is no reason not to leverage that capability to the rest of your network. /SWAG My gut instinct says that mobile operators will be a major player in v6 adoption.
