Overview
In Anycast, a request is routed to the 'nearest' or 'best' destination as determined by the routing protocol (usually BGP).
Benefits
- Low Latency: Users are automatically connected to the closest server.
- Load Balancing: Traffic is naturally distributed across multiple sites.
- DDoS Mitigation: Attack traffic is spread across many servers, making it harder to overwhelm a single target.
Common Uses
DNS (e.g., 8.8.8.8) and Content Delivery Networks (CDNs).
