ISP proxy
An ISP proxy is a proxy whose IP address is registered to a consumer internet service provider but runs on a server in a datacentre, combining an address that does not read as a hosting range with the throughput and uptime of hosted hardware.

Where an ISP proxy's address comes from
Every public IP block is announced to the internet by an autonomous system, and lookups show which organisation that network belongs to. An ISP proxy's address sits in a range announced under a consumer provider's ASN, while the box that forwards your traffic is hosted in a datacentre.
That split is the whole product: a site checking the registration sees an ISP, while you get the stable connection of a server rather than of somebody's home router.
ISP proxy vs residential proxy
| ISP proxy | Residential proxy | |
|---|---|---|
| Exit hardware | Hosted server | Subscriber's home connection |
| Stability | Consistent; no household line to drop | Varies with the line behind each exit |
| Price per GB on ARC | Lowest we sell (ARC Basic) | Higher (ARC Fast, ARC Ultra) |
| Where it falls short | Targets that look past the registration | Cost on high-volume plain HTML |
A full residential proxy is the step up when an ISP exit is treated as infrastructure.
Rotating and static ISP proxies
ISP addresses are sold in two shapes. A rotating pool hands out a different address per connection and is billed per GB — on ARC that is ARC Basic, which also takes _country- and _city- tokens. A static ISP proxy is one dedicated address, priced per IP per month with unmetered traffic, for jobs that need the same origin every time; see static ISP proxies.
When to choose an ISP proxy
Plain HTML fetched at volume: price monitoring, uptime checks, rank tracking and feeds that run around the clock. Start there and move only the targets that fail to a residential pool.

Is an ISP proxy the same as a static residential proxy?
The two names are often used for the same idea: an address registered to a consumer ISP, hosted on a server. Whether it is static or rotating is a separate question — ISP addresses are sold both as dedicated monthly IPs and as rotating pools billed per GB.
Why are ISP proxies cheaper than residential proxies?
The exit is a hosted server rather than a consumer line, so traffic is cheaper to carry. On ARC, the rotating ISP pool (ARC Basic) is the lowest price per gigabyte of any plan.
Can ISP proxies target a city?
On ARC, yes. ARC Basic accepts the same country and city tokens as the residential pools, using the published metro list, which makes it usable for local rank tracking and regional price checks.
When is an ISP proxy not enough?
When the target looks beyond the address registration and treats hosted traffic as infrastructure, or when you need many concurrent exits against one strict site; ARC Basic is the smallest pool. Those jobs belong on a residential pool.
