ISP vs Residential Proxies: Differences and Which to Choose
ISP proxies give one fixed address registered to an internet provider. Residential proxies rotate through home devices. How they differ in trust, speed, price and use.
Key takeaways
An ISP proxy, also sold as a static residential proxy, is one fixed address registered to an internet provider and hosted on a server.
A residential proxy sends traffic through real home devices and gives a new address per request or per session.
ISP proxies are billed per proxy with unmetered traffic. Residential proxies are billed per gigabyte.
Choose ISP for accounts and long sessions on one address. Choose residential for coverage, rotation and strict targets at volume.
Quick comparison
| Factor | ISP proxies | Residential proxies |
|---|---|---|
| Source of the IP | An internet provider's address hosted on a server | A home device on a consumer connection |
| What a site sees | An internet provider | An internet provider |
| Who else uses the address | Nobody, on a dedicated proxy | Other users of the pool, over time |
| How the IP changes | It does not change during the term | Per request or per session |
| Billing | Per proxy, traffic unmetered | Per gigabyte |
| Locations | A shorter list of countries | Most countries, down to the city |
| Speed | Server speed | Depends on the home connection |
| Best fit | Accounts, long sessions, antidetect profiles | Data collection, wide coverage, strict targets |
The short answer
An ISP proxy gives you one address that stays the same for the whole term. A residential proxy gives you a pool of addresses that keeps changing. Both addresses belong to internet providers, so neither looks like a server to a site that checks the network owner.
The choice depends on the task: one fixed identity for accounts, or many changing identities for collection at scale.
“An ISP proxy is not a cheaper residential proxy. It is one fixed address for one customer, worth buying where the same address has to come back every day.”
What an ISP proxy is
An ISP proxy is an IP address registered to an internet service provider but hosted on a server in a data center. The registration is what a site reads when it looks the address up, so it sees a home internet provider. The hardware is what you notice when you use it: server speed and a connection that does not depend on a home router.
The industry also calls ISP proxies static residential proxies. Static means the address stays assigned to you until the term ends. On a dedicated plan nobody else uses it.
What a residential proxy is
A residential proxy routes your request through a device on a home connection. The provider runs a pool of such devices and gives you a different one for each request, or keeps one for a session of minutes to hours.
Each address belongs to a real household connection, so the pool covers many countries and cities. The other side is control: the device behind a session can go offline, and the address goes with it.
Static residential and sticky sessions are not the same
Static residential is another name for the ISP product, not a setting of a residential pool. Some sellers also call a sticky session static, but a sticky session keeps a home device only while that device stays online. If you need the same address next week, you need an ISP proxy.
Ask two questions before you buy anything sold as static residential: does the address change when a device goes offline, and does anyone else use it.
Speed and stability
ISP proxies run on servers, so latency and throughput depend on the route to the target, not on someone's home connection. Residential speed varies with the device and the network it sits on.
For a scraper that sends thousands of small requests, the difference matters less than the block rate. For a long session in a browser, a connection that does not drop matters more than raw speed.
How the billing compares
ISP proxies are billed per proxy per month with unmetered traffic. On Proxya one ISP proxy starts at $2.50/proxy/mo, and a busy month costs the same as a quiet one.
Residential proxies are billed per gigabyte, from $2.40/GB on Proxya. You pay for the traffic the task uses, which suits work spread across many addresses.
Where ISP proxies win
Account management on social networks, marketplaces and ad platforms, where the account expects the same address at every login.
Antidetect browser profiles that need one stable address each.
Long sessions in stores and dashboards that end when the address changes.
Where residential proxies win
Data collection across many pages and locations, where volume and coverage matter more than a fixed identity.
Price and search monitoring in many countries and cities.
Targets that limit the number of requests per address, where a new address on each request keeps the job running.
Where datacenter proxies fit
Datacenter proxies are the third option. They are fixed addresses like ISP proxies, but registered to hosting companies, so a site that checks the network owner sees a server. They cost less than both and suit targets that do not check.
If a task works on datacenter addresses, there is no reason to pay for ISP or residential proxies.
How to decide
Start with the target. If it accepts datacenter addresses, use them. If it checks the network owner and you need the same address for weeks, choose ISP. If it checks the network owner and you need many addresses, choose residential.
Then test on the real target: one ISP proxy for a month, or a small amount of residential traffic, and compare the share of completed tasks.
Frequently asked
Neither is better in general. ISP proxies give one fixed address for accounts and long sessions. Residential proxies give many changing addresses for coverage and volume.
Yes, when the address is fixed and registered to an internet provider. A sticky session from a rotating home pool is sometimes also called static, but it changes when the device goes offline.
It depends on the traffic. ISP proxies are priced per proxy with unmetered traffic, from $2.50/proxy/mo on Proxya. Residential proxies are priced per gigabyte, from $2.40/GB. Heavy traffic on a few addresses favours ISP, light traffic across many addresses favours residential.
Residential for strict targets and wide coverage, datacenter for targets that do not check the network owner. ISP proxies suit scraping only when the job needs a fixed identity, for example behind a login.
By the registration, usually not: both belong to internet providers. Some IP databases also mark ranges that are hosted on servers, even when the owner is an internet provider, so test on the real target.
The one your target requires. If you are unsure, start with one ISP proxy for an account task or a small amount of residential traffic for a collection task, and measure the result.
