What is Anycast?

Anycast is a way to use Internet routing protocol (BGP) to steer traffic to the closest location in term of network hops. Basically, many servers around the world share the same IP address, and the traffic is routed to the closest available location automatically. If any of those servers becomes unavailable, the traffic is automatically re-routed. The advantage of this solution is two folds: it provides low latency and high availability.

NextDNS deployed its own anycast network (AS34939) to provide best latency and high availability. On top of anycast, NextDNS official apps implement advanced routing and fallback algorithms to further improve the latency and reliability of our service.
