Comcast, long active in the IPv6 arena have announced that they will be doing a native residential IPv6 deployment in Pleasanton, CA, on the edge of the San Francisco Bay Area, which will be a dual-stacked, native v4/v6 deployment with no NAT.
This is a much needed move to try and break the deadlock that seems to have been holding back wide scale v6 deployment in mass market broadband providers. Apart from isolated islands of activity such as XS4ALL‘s pioneering work in the Netherlands, v6 deployment has largely been available only as an option from providers focused on the tech savvy user (such as A&A in the UK).
Sure, it’s a limited trial, and initially aimed at single devices only (i.e. one device connected directly to the cable modem), but it’s a start, and there’s plans to expand this as experience is gained.
