A shared proxy is an IP address used by multiple users simultaneously. The cost is split among users, making shared proxies the most affordable option.
The proxy provider assigns the same IP address or pool to several customers. Each user sends requests through the same IP. The proxy server handles traffic from all users concurrently. Because the IP is shared, one user sending too many requests can affect the reputation of the IP for all other users.
The decision rule: do the target and the budget favor this type over the alternatives?
USER-shared-session-task01Everything lives in the username -- add "shared" to any proxy credential to apply shared 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 student uses a shared datacenter proxy to access geo-restricted academic journal databases that their university subscribes to from an off-campus location.
Shared proxies are budget-friendly for low-volume tasks, but you share the IP reputation with other users. If another user abuses the IP, your requests may get blocked too.
It depends on the provider. Some share an IP among 3-5 users, others among 20 or more. Fewer users per IP generally means better performance and reputation.
Avoid shared proxies for tasks where IP reputation matters, such as managing accounts or accessing sites with strict anti-automation measures. Use dedicated or residential proxies instead.
