# ISP proxy

> A datacentre-hosted address registered to a consumer ISP. Datacentre speed with residential registration, billed per IP.

**An ISP proxy — sometimes called a static residential proxy — is hosted on datacentre infrastructure but uses an address registered to a consumer internet provider.** It is a deliberate hybrid.

## What the hybrid buys you

| Property | Behaves like |
| --- | --- |
| Speed and uptime | [Datacenter](/glossary/datacenter-proxy/) |
| Network registration | [Residential](/glossary/residential-proxy/) |
| Billing | Per address per month, not per gigabyte |
| Address stability | Static — the same address every time |

## When it is the right choice

Work that needs a consistent identity over time: maintaining a logged-in session, managing an account, or any task where an address that changes every request would itself look wrong. Because billing is per address rather than per gigabyte, ISP proxies also suit high-bandwidth work that would be expensive on a residential plan.

## The limitation

Volume. A residential pool can offer very large numbers of addresses; an ISP allocation is a fixed list you are renting, and burning those addresses through careless use is expensive.
