Deployment Update

IPv6 has been launched on all Arris DOCSIS 3.0 C4 CMTSes, covering over 50% our network.  We are targeting completion of the rest of the network by mid-2013. Our progress has led to nearly 2.5% of our Xfinity Internet customers  actively using native dual stack. Additionally, IPv6 traffic has increased 375% since World IPv6 Day in June 2011.  Following World IPv6 Launch in June 2012 Comcast also observed that approximately 6% of the 2012 Olympics served over YouTube to Comcast customers was over IPv6.
