A semi-dedicated proxy is an IP address shared among a small group of users, usually two or three, instead of one user or a large pool. It sits between a fully dedicated proxy and a shared proxy in terms of cost and performance.
The proxy provider assigns the same IP address to a limited set of accounts, typically capped at two or three users. Each user connects independently and sends their own requests through that shared IP. Because so few accounts share the address, the load stays much lower than on a fully shared proxy pool, which keeps speed and reliability closer to a dedicated proxy. The provider tracks usage per account so no single user can overload the connection.
The decision rule: do the target and the budget favor this type over the alternatives?
USER-semi-dedicated-session-task01Everything lives in the username -- add "semi-dedicated" to any proxy credential to apply semi-dedicated proxy to a single task. Swap "task01" for a new label to spin up an independent, isolated identity.
Not every proxy type gets treated the same way -- reach for this type when the target’s defenses call for it.
Decide per task whether a fresh IP or a sticky session fits better -- both draw from the same pool.
Every KnoxProxy plan charges for successful-response bandwidth only, so testing this type costs nothing extra in fees.
Scale this proxy type up without a plan change -- concurrent connections are unlimited on every tier.
A small marketing team splits the cost of a semi-dedicated proxy with another business to get near-dedicated speed at a lower price.
Semi-dedicated proxies let budget-conscious users get better performance than a fully shared proxy without paying full price for a dedicated one. This makes them a practical option for smaller projects that still need decent speed and uptime.
Semi-Dedicated Proxy is one of several proxy types available for routing traffic. Each type trades off trust, speed, cost, and coverage differently, and most production setups use more than one.
Most providers cap semi-dedicated proxies at two or three accounts sharing a single IP address, never more. This is a small enough group that speed and reliability stay close to what a fully dedicated proxy offers, without one heavy user degrading performance for the rest of the group.
Yes. Since the cost of the IP is split between two or three users instead of one, semi-dedicated proxies usually cost less per person than a fully dedicated proxy, while still offering solid speed and reliability close to what a dedicated connection provides on its own.
