ISP proxy
Also called: static residential proxy, static resi
An ISP proxy is an IP address registered to a consumer internet provider but hosted in a datacenter. It combines the residential registration that makes an address look ordinary with the stability and speed of server infrastructure, and it is normally sold per IP rather than per gigabyte.
ISP proxies exist because the two properties people want usually come apart. Residential addresses look right but come from consumer devices that go offline. Datacenter addresses are fast and always up but announce their hosting origin. An ISP proxy is an address an internet provider has registered as residential, operated on hardware that never sleeps.
What you get
- A fixed address you keep for as long as you pay for it — no rotation to manage.
- Datacenter-grade speed and uptime, without the residential pool’s variability.
- Flat per-IP pricing, which makes cost predictable regardless of traffic volume.
The limitation
The address is static, so it accumulates history. That is exactly what you want for an account meant to live in one place for months — and exactly what you do not want if the address ever picks up a bad reputation, since you cannot walk away from it the way you can from a rotating pool. Availability is also narrower: ISP ranges exist in far fewer countries than residential pools.
For a fleet, ISP proxies suit long-lived accounts that log in from the same place every day, while rotating residential suits shorter or higher-volume work.
