Many have surely heard of Anycast. With this method of network addressing and routing, a single IP address is assigned to multiple servers in the network. These servers can even be located in data centers that are far apart. The idea of Anycast is that, depending on the location of the request sources, the data is sent to the closest server (according to the network topology, more precisely ā BGP routing protocol). Thus, […]
