What is BGP Anycast?
Anycast is a way to route network traffic that dramatically increases the speed and reliability of your data, application, and content delivery to your end users. With anycast routing, one IP address becomes reachable at multiple geographic locations. The many benefits to using anycast routing include:
BGP Anycast Use Cases
From CDNs to DNS, learn how anycast can reduce latency and eliminate downtime for your end users.
Performance and HA
At the network level, BGP anycast can offer unparalleled low latency delivery and reliability.
Providers can use anycast to improve their customers’ internet browsing experience.
Using anycast, recursive lookup requests can be resolved by the nearest authoritative DNS server.
If a server at goes down, traffic can be seamlessly rerouted to a backup site with anycast.
CDN providers frequently use BGP anycast to route traffic to geographically distributed edge servers.
Provide your end users an optimal experience when accesing a hybrid infrastructure.
Many providers use BGP anycast to ensure high performance when adding security layers.
Using anycast can ensure low-latency connectivity both to – and within – an overlay network.
IPv6 native since 2008, our anycast platform allows direct packet-level access with IPv4, IPv6, or both.
We partner with anycast providers who require a flexible, purpose-built, highly available network.
Anycast vs Unicast
One the the easiest ways to understand anycast routing is to compare it to the more commonly-used unicast routing.
Unicast to Multiple Locations
With unicast routing, all requests are directed to one point of presence, leaving users frustrated when servers at that location go down.
User requests are sent to the point of presence they are physically closest to. If one point fails, users are immediately sent to the next closest location.
