Term:Point of Presence

A point of presence (PoP) is an artificial demarcation point or network interface point between communicating entities. A common example is an ISP point of presence, the local access point that allows users to connect to the Internet with their Internet service provider (ISP). A PoP typically houses servers, routers, network switches, multiplexers, and other network interface equipment that connects an ISP to customers including OLTs (optical line terminals) for fibre internet, and is typically located in a data center. ISPs typically have multiple PoPs. PoPs are often located at Internet exchange points and colocation centers.

One example of a point of presence is a 44Net Connect node. This centralized device uses WireGuard tunnels to route traffic to 44Net devices that do not directly advertise their 44Net IP assignments.
