Comcast Successfully Deploys Cisco Network Registrar for DHCP and DNS Services for IPv4 and IPv6

IPv4 addresses have run out. Many service providers today are implementing or beginning to plan for the transition to IPv6. One service provider at forefront of this activity is Comcast, one of the nation’s largest video, high-speed Internet and phone providers to residential and business customers. Starting in 2005, Comcast began putting together deployment plans for IPv6 in order to address the IPv4 address run-out and to be ready to offer their customers new services that take advantage of IPv6. The Comcast IPv6 program is run by John Brzozowski, Distinguished Engineer & Chief Architect for IPv6.

According to Mr. Brzozowski, one of the fundamental objectives of this ongoing program is to ensure that the introduction of the technology is seamless and not disruptive to their subscribers. With over 49 million customers relying on these services, even front-end tasks like ensuring feature parity between IPv4 and IPv6 were “Herculean” efforts. For example, for the mission-critical task of device provisioning, there needs to be support for DHCPv6 to ensure the devices get provisioned tomorrow (with IPv6) like they are today (in IPv4).  Using Cisco Network Registrar for DHCP and DNS, Comcast is able to leverage the same software platform and functionality by using a dual-stack IPv4/IPv6 approach. In fact, with Cisco Network Registrar, Comcast has been able to move way beyond feature parity and has implemented features from device management to advanced subscriber services for both IPv4 and IPv6.

In the following video, Mr. Brzozowski sat down with Cisco to share some highlights of the Comcast IPv6 program and how Cisco Network Registrar is helping them make the transition for DHCP and DNS services.
