Basic Internet Connectivity And Modem Help

Well the number of Internet subscribers out there isn't getting any smaller, so eventually you guys are going to run out of your allotment.  When (or before) that happens, you'll have to either get another one from ARIN, or buy one from a third party at a rather inflated price.  Eventually, you'll probably just decide that it's more efficient to implement carrier-grade NAT.

What's the timeline on this?

Oh and when you guys actually go through with it, please use the 100.64.0.0/10 block.  AT&T is doing CGN with 10.0.0.0/8, and it has a lot of people having to make configuration changes.  Judging by the forum postings there, they are all angry.

From their FAQ on Comcast6.net:

No, Comcast is not deploying tunneling or Large Scale NAT (LSN) at this time. We are using Native Dual Stack, which means a customer gets both IPv6 and IPv4 addresses simultaneously. As a result no tunneling or Network Address Translation (NAT) is necessary. We believe this approach offers meaningful performance benefits to our customers compared to the alternatives.

All we can say is that we have no current plans to use LSN / CGN now or in the near future. And this may indeed be a key service differentiator in the marketplace in the future.

Thank you. Really.

The dual stack is working good here. Everyday I notice more website using IPV6. I shutoff the IPV4 and check different websites, like the VA for example. Yep the VA has now transitioned to ipv6 now. ipv4 and ipv6 speeds are the same. In the last week the ipv6 ping times are much better. We are in Arris country here.

@Reese:  You might be interested in either IPvFoo (Chrome) or IPvFox (Firefox).  Note that Chrome and Firefox both implement rapid fallback to IPv4 sockets if IPv6 is taking too long.  Veterans Affairs has also announced that they will kill IPv4 sometime in 2014 (October, I think).  I'm wondering what that's going to do to the older Vietnam generation who may not know so much about this stuff.

@Comcast:  Any knowledge of when you plan to enable dual-stack on the Ubee modems?
