What is Sticky IP?
An IP address that remains assigned to your session for its duration, as opposed to rotating on each request.
A sticky IP is the address behind a sticky session. From the target's point of view it is simply a visitor who stayed on one connection, which is what any real user looks like.
Stickiness on a residential network is best-effort rather than guaranteed. The address belongs to a real consumer device, so if that device goes offline the session ends early and the provider hands you a replacement.
When a session must not break, an ISP proxy is the stronger option: the address is rented to you outright for the billing period and does not depend on someone else's device staying connected.
