Peering vs IP Transit: What’s the Difference?

Peering and IP transit both connect networks, but they serve different purposes. Understanding the distinction helps network operators plan reachability, performance and cost.

What is peering?

Peering is the exchange of traffic between networks, commonly at an internet exchange or through a private interconnection. The scope depends on the routes each participant advertises.

What is IP transit?

IP transit provides reachability to the wider internet through an upstream network. It is used where direct peering alone cannot provide complete coverage.

Why networks combine them

A network may peer with important destinations while using transit for comprehensive reachability. The right mix depends on traffic, locations, policy and operational capability.
