Comcast has begun the production rollout of its new IPv6 service, with 100 customers upgraded in San Francisco’s East Bay in one week.
IPv6 is an upgrade to the Internet’s main communications protocol, which is called IPv4. IPv6 features an expanded addressing scheme that can support billions of devices connected directly to the Internet at faster speeds and lower cost than IPv4, which is running out of addresses.
Comcast began an IPv6 trial 18 months ago and is a leader in the deployment of IPv6-based services among U.S. ISPs.
The production rollout began on Oct. 31. It offers customers “native dual-stack service,” which means Comcast is supporting both IPv6 and IPv4 services.
The initial subscribers of Comcast’s production-quality IPv6 service have stand-alone computers running Microsoft Windows 7, Windows Vista or Apple Mac OS X that are connected directly to a Comcast cable modem. Comcast plans to support IPv6 for customers with home routers at a later date.
