The document discusses IPv6 deployment and the challenges of a complex transition from IPv4. It proposes a "divide and conquer" approach with three stages: 1) enabling IPv6 connectivity for users first before upgrading network internals, 2) leveraging content delivery networks to accelerate IPv6 availability of content, and 3) simplifying legacy IPv4 support through IPv4-IPv6 translation in the long term. This staged approach addresses critical business needs and aims to promote IPv6 adoption incrementally despite technical difficulties of a full transition.

› Tier-1 carriers and large service providers IPv6-ready
› Small service providers on less aggressive schedule
