ARRIS’s DOCSIS 3.0 C4 CMTS and Touchstone WBM760 Wideband cable modems, using generally available software, have been successfully deployed for an IPv6 services trial by Comcast in the MSO’s Denver area systems. The trial featured a live application of native dual stack (IPv4 and IPv6 simultaneously) CPE support.

“Over the past year we’ve worked very closely with our customers to plan IPv6 feature support for both our C4 CMTS and our Touchstone CPE portfolio of cable modems and E-MTAs,” said Todd Kessler, ARRIS VP, CMTS Product Management, in a statement.

Since 1981, IPv4 has been the publicly used Internet Protocol and is currently the foundation for most Internet communications. The exponential growth of the Internet and the traffic it enables has created a need for more addresses and IPv6 fills that need. The last block of free IPv4 addresses was assigned in March.
