Anycast is a network addressing and routing method that allows multiple servers to share the same IP address. When a request is sent to this shared address, the network routes it to the nearest server based on factors like distance or network topology. This helps improve response times and reliability. This technique is commonly used in content delivery networks (CDNs) and Domain Name System (DNS) services. By directing user requests to the closest server, Anycast enhances performance and reduces latency, making it an effective solution for distributing web content and services globally.
