ISP proxies: what are they, and why call them static residential?
An ISP proxy uses an address that an internet service provider registered as residential, then keeps it fixed for you. Sites see a household line, yet unlike rotating residential it stays identical for the entire term you order. Any history built on that address carries through the whole period.
Datacenter proxies are fixed too, but they sit in hosting company ranges, while rotating residential gives location freedom at the cost of a changing address. ISP proxies pair residential credibility with a fixed, dependable address. For account work that needs a constant address, it is the first product to consider.
Compared with mobile proxies, the difference is the network: wired lines instead of cellular. That is why many people search for them as static residential proxies.
