What is an Internet exchange point? This is a name given to a place on the Internet where many networks interact. It is usually called an IP address or IP pool. On the Internet itself, the term exchange points are called ports. A typical Internet server consists of an IP address, an optional port, and security features that allow communication between other systems on the Internet.
An exchange point on the Internet allows users from various computer systems on the Internet to send and receive traffic on the same network. This traffic is routed to the destination through a protocol, usually a layer two protocol such as Hypertext Transport Layer 2 or TCP/IP. In the simple scheme of things, the IP address of one system corresponds to a distinct number, typically a 32-bit number, assigned to that system by an IP server.
