IPv6 Pilot Market Deployment Begins
Wednesday, November 9, 2011

Comcast has started our first pilot market deployment of IPv6 a limited part of California. This first phase supports directly connected CPE, where a single computer is directly connected to a cable device. A subsequent phase will support home gateway devices. To learn more, check out FAQs on the pilot market deployment and the announcement and technical details on our blog.


IPv6-Based DNS Servers Available
Tuesday, August 30, 2011

We now have IPv6-based DNS servers available for customers to use as their recursive DNS servers. These are Anycast-based and so you need only use two IP addresses, no matter where in our network you are located. These are now available for use on a beta testing basis at the IP addresses 2001:558:FEED::1 and 2001:558:FEED::2.


World IPv6 Day Begins This Evening
Tuesday, June 7, 2011

World IPv6 Day begins this evening in the U.S. Comcast will be continuously monitoring our network and customer contact volume closely during this event, from an IPv6 command center in Philadelphia. We anticipate that the overwhelming majority of our customers should not experience any difficulty accessing participating web sites. Nevertheless, if a customer does have difficulty, they can run a simple test to see if World IPv6 Day is the cause, by visiting http://test-ipv6.comcast.net. If a problem is discovered, instructions are be provided on that page. In addition, for Windows users that experience a problem, Microsoft has released a special fix. If customers need additional help, they should visit our customer forums.


DOCSIS-Based Native Dual Stack Trial Expands
Monday, June 6, 2011

We have recently expanded our DOCSIS-based IPv6 Native Dual Stack trials to select locations in the following metropolitan areas: San Francisco, CA, Philadelphia, PA, Miramar, FL, and Chicago, IL. This round of expansion includes the addition of home network equipment from D-Link. The successful expansion of our trials is a clear indicator of the Comcast’s and the cable industry’s readiness for IPv6. One important benefit of this event is to continue to exercise and prepare the infrastructure that we will use to deliver IPv6 to our subscribers.
