Internet Evolution and IPv6#
ARIN 56 Public Policy and Members Meeting digest Program Adjacent pick 30–31 October 2025
Geoff Huston AM, Chief Scientist, APNIC
- Why: The best strategic talk on the program. Huston connects trends the PM cares about — edge delivery, the end of per-core performance scaling, and why the DNS has quietly become the Internet's identity layer.
- What: The argument: abundant fiber capacity, compute, and storage shifted provisioning from on-demand to just-in-case, shrinking "packet miles" and pushing service to the edge. The warning: processor clock speeds topped out a decade ago, so the IPv4-workaround stack (NAT, dynamic naming, content steerage) embeds ever more per-packet processing into infrastructure that no longer scales exponentially — IPv6 is the complexity-reduction escape valve, which is what India's and China's adoption curves show. The reframe: identity and authenticity credentials now attach to service names, not IP addresses; IP addresses are mere topology tokens dynamically bound by DNS — and that binding is masking dual-stack, removing traditional pressure from the IPv6 transition.
- How: A synthesis of capacity, compute, and adoption trend data rather than a mechanism; the "application is the service" framing ties CDN/edge architecture to naming and identity.
- Where applicable: General and vendor/region-agnostic; most useful as input to multi-year network strategy and IPv6 business cases rather than immediate operations.
