Peering is a process by which two Internet networks connect and exchange traffic. It allows them to directly hand off traffic between each other’s customers, without having to pay a third party to carry that traffic across the Internet for them. Peering is distinct from transit, the more usual way of connecting to the Internet, in which an end user or network operator pays another, usually larger, network operator to carry all their traffic for them.

An Internet Exchange Point is where Internet networks come together to peer or exchange traffic between their networks. Internet exchange points are not Internet service providers. While they allow network operators to exchange traffic with other network operators, an exchange point will not sell you anything resembling complete Internet connectivity. They are, instead, one of the building blocks around which the Internet is built.

Every device connected to the Internet needs a unique Internet Protocol (IP) address so it can communicate with other devices. IP addresses identify devices within networks, allowing the Internet’s routing system to transfer packets of data between hosts (such as a computer, website, or mobile device). IPv4 and IPv6 are the forms of IP addresses in use today.
