The exit node is the final server or device in a proxy chain whose IP address the target website sees. In a residential proxy network, the exit node is the actual consumer device — a phone or desktop — routing your traffic through its connection to the internet.
Exit node location determines the apparent geographic origin of your traffic. Understanding the full request path — your client → proxy infrastructure → exit node → target — matters for debugging latency issues: slow or overloaded exit nodes are often the bottleneck, not your bandwidth. Exit node health and speed vary significantly within large residential proxy pools.
