ISP and static residential proxies: one category with two names
ISP proxy and static residential proxy are two market labels for the same product category in this dataset. Webshare states the equivalence directly, so the dataset uses isp as the canonical type instead of counting the two search terms as separate technologies.

The category centers on addresses sold with some form of retention or stable assignment. That is not a guarantee that every ISP offer has the same retention period. Retention remains a plan-level field, and when a vendor does not publish it, the value is not published. Proxy price data methodology and evidence
“Static” is not a complete plan description
The name does not establish whether the address is dedicated or shared, how long it is retained, or whether the product also supports rotation. Litport sells both static and rotating variants from its static residential pricing surface. A buyer who needs one unchanged address must therefore require the exact rotation and retention terms rather than relying on the category name.

Billing is also separate from identity. Many ISP offers sell an address count, but traffic-priced and configurable offers remain ISP products. A per-IP bill does not prove the network category, and a per-GB bill does not turn an ISP offer into a rotating residential product.
How ISP differs from the other three types
| Compared type | The useful boundary |
|---|---|
| Datacenter proxy services | Both can provide retained or dedicated addresses. ISP is the provider’s ISP or static residential category, while datacenter is the provider’s datacenter category. Billing alone cannot separate them. |
| Residential proxy services | ISP usually centers on a purchased address and its retention behavior. Residential usually centers on access to residential inventory through rotating or sticky sessions. A sticky session is not the same as a purchased static address. |
| Mobile proxy services | Mobile offers can add cellular network, carrier, device, or mobile-location claims. ISP retention does not imply a mobile carrier connection. |
The terms “dedicated,” “shared,” “static,” and “rotating” remain modifiers inside the category. They should be recorded independently, as should traffic state, concurrency, and location controls. Not published never means unrestricted.
What belongs in the buying decision
The type explainer answers what ISP and static residential mean and why the two names map to one category. The ISP category buying guide owns the market-wide price range, exact receipts, package steps, bandwidth disclosure, ISP-versus-residential cost examples, and buying sequence.
That split leaves one simple boundary test here: choose the ISP column only when the provider’s ISP or static residential classification and its published address-retention behavior are requirements. Price and compare only after the address count, sharing model, retention term, rotation mode, and traffic state are known.
