Anycast vs Non-Anycast Network
NetworkNon-anycast DNS routes all queries to a single server regardless of distance, causing high latency. Anycast DNS advertises the same IP from multiple locations, so each client is automatically served by the nearest edge.
Non-Anycast (Left)
- Single server handles all traffic
- Distant clients experience high latency
- Single point of failure
Anycast (Right)
- Multiple servers share the same IP
- Clients are routed to the nearest server
- Built-in redundancy and load distribution
