Proxies and networking

ISP proxy

Also called static residential proxy, static ISP proxy, dedicated ISP proxy

Definition

An ISP proxy, sometimes called a static residential proxy, is a proxy that runs on a server in a data centre but uses an IP address registered to an internet service provider, combining server speed with an address that looks like a consumer connection.

How it works

An internet provider can lease or route some of its address ranges to a hosting company. Proxies run on servers in that company’s racks, but the IP addresses still belong to the provider’s network, the one its number in the routing system (its ASN) names. To a site that looks up who owns an address, the visit appears to come from that provider rather than from a hosting firm.

ISP proxies are usually rented per IP address and keep the same address for as long as you rent it. That is why they are also called static residential proxies, although no household is involved.

Why it matters when you run several accounts

A logged-in account does best with an address that doesn’t change, and an ISP proxy gives you one with server-class speed and uptime. How residential it looks depends on the range: lookup services can see the network and, in some cases, how the range is used, so quality varies a lot between providers. Treat the label as a claim to test, not a guarantee.

How SoftGlaze Browser handles it

Add an ISP proxy like any other, as HTTP and SOCKS5, with or without a login, and assign it to one profile so that profile keeps one address. The check shows its exit IP, country, latency and whether the address is on any of 3 DNS blocklists, and a health grade from A to F. The Sticky rotation policy keeps a profile on its own fixed proxy.
