As AI moves into production, every inference call becomes a real‑time decision about where workloads should run—cloud, on‑prem or edge. This whitepaper explains how a DNS‑driven control plane provides the globally distributed, policy‑enforced decision layer needed to route AI traffic based on latency, cost, model health, privacy and carbon impact. It outlines practical DNS‑first coordination patterns for agent‑based systems, demonstrates how intelligent routing prevents outages and improves resilience and shows why DNS is uniquely positioned to become the durable control plane for AI‑native enterprises.
