ISP proxies combine the trust of an ISP-registered IP with datacenter speed and a fixed address. What they are, what they are good at, and when not to use them.
An ISP proxy, also called a static residential proxy, is an IP address registered to a consumer internet provider but hosted on a fast server. You keep the same address for as long as you rent it, usually a month at a time, and you pay per IP rather than per GB.
How they differ from residential and datacenter
- vs datacenter proxies: the IP belongs to an ISP's network (its ASN) instead of a hosting company, so sites that filter out cloud and hosting ranges treat it like a normal subscriber.
- vs rotating residential: the IP never changes, the connection does not depend on someone's home device being online, and speed is close to datacenter speed. Traffic is usually unmetered or very generous.
What they are good at
- Long-lived accounts. One account, one IP, for months. That is how a normal user looks.
- Anti-detect browser profiles that should keep a stable identity.
- Services that whitelist your IP, such as an API or admin panel that only accepts known addresses.
- High-bandwidth jobs on friendly targets, where paying per GB would get expensive.
When not to use them
- Large-scale scraping of strict sites. A handful of fixed IPs gets rate limited quickly. Rotation over a big pool works better.
- Precise city targeting. ISP proxies come in a limited set of locations.
- Burner tasks. If you need a fresh IP every few minutes, a fixed IP is the wrong tool.
Tips for using a static IP well
- Keep one IP per account or profile, and do not share it across unrelated accounts.
- Match the browser's time zone and language to the IP's country.
- Warm up new accounts slowly: normal browsing before heavy automation.
- Check the IP's reputation before you use it for something important, and ask for a replacement early if it is already flagged.
Pricing
ISP proxies are billed per IP per month. On Proxare they start at $1.39 per IP, with lower prices the more you take.
