Content Delivery Networks - CDNs
In order to get information to end users more quickly, many applications are distributed from multiple geographical points-of-presence (PoPs) using Content Delivery Networks (CDNs). Each PoP can host many IPs to deliver an application. A sample IP is provided.
Take special note of CDNs that use Anycast technology. Anycast makes it possible to route a single IP address to a variety of different geographic locations. In other words, one global Anycast IP is hosted in multiple geographic locations.
