Quick answer
What is an ISP proxy, in one sentence?
An ISP proxy is a fixed IP address registered to a consumer internet provider, such as AT&T or Comcast, and hosted on a server in a data center; vendors also call it a static residential proxy. PinnedIP rents US ones from $2.03 per IP for 30 days (October 2026), no KYC.

Glossary: FAQ
Is "static residential" the same as "ISP"?
Yes, in practice. Both names describe a fixed address registered to a consumer provider and hosted in a data center.
Is "dedicated" the same as "private"?
Vendors use both words for an IP used by one customer at a time. Neither means the traffic is hidden from the proxy operator: we keep connection metadata for abuse handling, as the privacy policy explains.
