Anycast DNS
Anycast is a network addressing method where the same IP address is announced from multiple geographic locations. In [[dns|DNS]], anycast routing directs queries to the nearest server, improving performance and providing DDoS resilience.
Example
Cloudflare's 1.1.1.1 DNS resolver uses anycast — your query is handled by the closest data center, whether in Tokyo, London, or São Paulo.
