Registry Anycast DNS Performance and Global Latency Benchmark
Authoritative technical benchmark evaluating the global Anycast networks that power root servers and top-level domain registries. Measures median and P95 DNS resolution latency across six continents, Anycast Point of Presence (PoP) density, and DDoS defense capacity.

Autonomous System Numbers (ASNs) & Anycast Resilience
Unlike unicast addressing where a single IP address corresponds to one physical host, Anycast DNS announces the exact same IP prefix from hundreds of Points of Presence (PoPs) worldwide using BGP. Resolvers on the internet automatically route UDP queries to the topologically nearest datacenter via standard internet routing metrics.
This architecture delivers two critical security and performance properties for TLD registries: First, latency is minimized because queries are terminated locally rather than traversing transoceanic fiber cables. Second, volumetric Distributed Denial of Service (DDoS) attacks are geographically localized and absorbed by individual edge nodes without cascading to the global root zone.
