ISP proxy
An address registered to a consumer ISP but hosted in a data centre — datacenter speed and stability with residential registration.
Also called: static residential proxy.
An ISP proxy, also sold as a static residential proxy, sits between the two other kinds. The address is registered to a consumer internet service provider, so a lookup of who owns it returns an ISP rather than a hosting company, but the machine answering is in a data centre. That combination buys the stability and speed of datacenter infrastructure with a registration that reads as consumer, and because the address is dedicated to you it does not rotate or get shared with whoever else is on a pool.
The honest caveat is that how a site treats one depends on the data that site has, not on how the address was marketed to you. Some platforms classify by the registered owner and see an ISP; others maintain their own lists and know the range sits in a facility. That is a question to answer empirically against the platforms you care about rather than from a vendor's description. Argus reports what an exit actually looks like — the egress IP, the country, whether it sits on a datacenter network and which provider runs it — and separately sweeps real destination sites through each proxy so a row can name what refused it. Both are on the proxies page.
More from the glossary
Mobile proxy
A proxy exiting through a carrier network, where one address is shared by thousands of real phones — which is what makes it tolerant.
SOCKS5
A general-purpose proxy protocol that forwards TCP connections without inspecting them, optionally behind a username and password.
Proxy rotation
Changing the exit address automatically — per request or on a timer. Right for collecting public pages, wrong for a signed-in session.
Multi-accounting
Running several accounts on one platform from one machine without them being read as one operation.
Account linking
A platform deciding that two accounts belong to the same operator, from storage, device, network or behaviour.
Device entropy
How much identifying information a device's reported properties carry — measured in bits, and lowered by looking ordinary rather than by hiding.
