Unbuckling the narrow waist of IP: Addressing Agility for Names and Web Services

What this post added

This post introduces 'Addressing Agility,' a novel approach to decouple IP addresses from names and services. It argues that IP addresses should represent reachability, not names, and proposes an inversion of the traditional DNS lookup process. Instead of pre-assigning IP addresses to names, policies are defined with attributes (e.g., location, account type) that map to pools of equivalent IP addresses. These addresses are then assigned dynamically at query time, making the IP-to-name binding ephemeral and enabling greater flexibility in service provisioning, migration, and innovation.
