Comcast has begun the production rollout of its new IPv6 service, with 100 customers installed in San Francisco's East Bay in one week.

Comcast subscribers will soon have the option to place video calls through their television, thanks to a partnership with VoIP provider Skype announced on Tuesday. Customers will need additional equipment to use the new feature.

Really, is there anything anyone could add to this -- an explanation, some insight -- that could possibly make what is happening here more obvious? I don't think so.

The DoJ's requirement that Comcast let customers see non-NBC shows online may be the only protection business Internet users get from federal regulators.

Comcast and Time Warner Cable have joined the throng of network vendors that are participating in World IPv6 Day, a 24-hour trial of the next-generation Internet protocol scheduled for June 8.

Comcast may be the arch-enemy of consumers who want to watch video online, but it's far from the bottom in delivering good video.

Verizon isn't satisfied the sheriff responsible for enforcing net neutrality is blind, deaf and unarmed; it wants the law run out of town.

Comcast is testing a new set-top video box code-named Xcalibur that includes DVR capability, robust search capabilities and limited Web access, according to The Wall Street Journal. The new service will let users search for live, on demand and recorded television, offer social networking access, as well as a limited number of online videos. From the sound of it, Comcast is hoping to do what it always does: deliver preselected content to your television with limited user choice.

Shares of Netflix (NASDAQ: NFLX) jumped 6.98, or 3.5 percent, to 205.90 on Tuesday -- despite a nasty dispute between Comcast and broadband backbone provider Level 3 Communications that potentially could hurt the video-on-demand company's business. Earlier in the day Netflix shares reached another all-time high of 206.80.

Comcast has begun migrating its customers to a new Internet security mechanism that will help protect them from being inadvertently routed to phony Web pages for pharming attacks, identity theft and other scams.

Comcast last week installed the first corporate customer for its new native dual-stack service, which supports both IPv4, the current version of the Internet Protocol, and the long-anticipated upgrade known as IPv6.
