DHCPv6-PD + MAP

•  IPv4 is out, IPv6 is in

•  When managing devices, Comcast does more with IPv6 than IPv4 already, approaching 100% across our entire footprint

•  60-70% of our customers are native dual stack enabled today

Key Messages from

•  IPv6 is foundational for us – for innovation and as platform for all of our products and services

•  IPv6 will fuel advancements like IPV6 segment routing, service chaining, NFV, and SDN while IPv4 moves to a service on top of IPv6 (IPv4aas)
