Meet NetActuate at All Things Open 2025 in Raleigh Oct 13-14!
Learn how BGP Anycast can improve your infrastructure's performance, resiliency, and security at the network level.
BGP Anycast Explained
BGP Anycast is a way to route network traffic that dramatically increases the speed and reliability of networks. With anycast routing, one IP address becomes reachable at multiple geographic locations. Incoming requests from end users are automatically fulfilled to the server nearest to them on the network. This makes adding new locations or taking a server offline much simpler, as traffic automatically reroutes to the next nearest available location.
Nearly all major networks, CDNs, and cloud providers make use of BGP Anycast in some form, though their scope and purpose vary.
Anycast enables user requests to be directed to the location closest to them geographically, minimizing round-trip time (RTT), decreasing the number of hops, and reducing latency.
Anycast makes fully redundant servers available from one IP address. If one location is down for any reason, users are sent automatically to the next closest location.
Anycast routes users to the location closest to them, effectively balancing the load among your servers, while improving speed and performance.
Anycast reduces the impact of DDoS attacks. If one location is taken offline, users are automatically rerouted to the next closest online server available at the same IP.
Explore these common industry use cases to understand how BGP Anycast can reduce latency, prevent downtime, and improve user experience worldwide.
If one node fails, traffic is automatically rerouted to another location without interruption, maintaining uptime and service continuity.
BGP Anycast is a network addressing and routing technique that lets multiple servers in different locations all sit behind a single IP address. Anycast leverages Border Gateway Protocol (BGP), which is how networks exchange routing information on the internet.
Anycast networking distributes identical services across multiple global locations, with routing protocols directing users to the optimal node based on proximity and performance.
Deploy across 45+ global locations on one of the world’s largest networks, engineered for performance, resiliency, and efficient scaling without the risk of downtime or runaway costs.
