Anycast: A networking technique that allows multiple servers to share the same IP address, with the objective of distributing network traffic and improving availability and performance. When a user makes a request to an anycast IP address, the network routes the request to the nearest or best-performing server based on factors like geographic proximity, latency, and server load. This technique is widely used in content delivery networks (CDNs) and domain name system (DNS) services to ensure fast response times and resilience against outages or attacks. Anycast can also be used to improve redundancy and load distribution in addition to performance and availability.
