ISP proxies vs residential proxies is one of the most common questions buyers ask, because both show websites an IP address that belongs to a consumer internet provider. The difference is what sits behind that address and how you pay for it. An ISP proxy is one fixed IP that you rent per month and keep; a residential proxy is access to a large pool of real household connections that you pay for by the gigabyte and can rotate. This guide explains how each works, where each wins, what they cost in practice, and how to choose, with a clear recommendation for the most common jobs.
The short version
Choose ISP proxies when you need the same IP every day for a small number of accounts or long sessions, and residential proxies when you need many IPs, many locations or rotation. ISP proxies are priced per IP, are fast and stable, and target by country only. Residential proxies are priced per GB, cover more than 170 locations with city, ZIP and ISP targeting, and can give a new IP per request or keep a sticky session.

Intro. ISP proxies and residential proxies both give you an IP address that belongs to a home internet provider. So what's the difference, and which one should you pick? In the next few minutes you'll learn what each one is, how they compare on speed, rotation, targeting and price, and how to choose between them.
What is an ISP proxy? An ISP proxy is a static IP address registered to a consumer internet provider, but hosted on a server in a data center instead of in someone's home. Websites that look up the address see a home provider's network, and you get server-grade speed and uptime. That's why they're also called static residential proxies. In the ProxyEmpire dashboard, you'll find them under ISP Proxies.
What is a residential proxy? A residential proxy sends your requests through a real household's internet connection, chosen from a large pool. ProxyEmpire's pool has more than 30 million residential IPs in over 170 countries. You can get a new IP on every request, or keep one in a sticky session until you rotate it or the device behind it goes offline.
The key difference: one fixed IP or a pool. The biggest difference is what happens to the IP over time. An ISP proxy is one fixed IP that stays yours for the whole subscription. A residential proxy gives you access to millions of IPs, so you can change address whenever you want, but no single home IP is yours to keep. If a household's device goes offline, that IP goes with it.
Speed and stability. ISP proxies are usually faster and steadier. They run on servers with data center connectivity, so speed and uptime are high and consistent. Residential speed depends on each household's connection, so it varies from one IP to the next. For long sessions that must not drop, that difference matters.
Rotation and targeting. Do ISP proxies rotate? No. You keep the same IP for the rental period, and if you need a new one, you add another IP. Residential proxies can change IP on every request, rotate on a timer of up to two hours, or stay sticky. Targeting differs too. ISP proxies are chosen by country, in 24 countries. Residential proxies target country, region, city, ZIP code, ISP and ASN, at no extra charge.
Pricing: per IP or per gigabyte. They're also billed in different ways. ISP proxies are billed per IP per month, with unlimited traffic under a fair-use cap of 100 gigabytes per IP. Residential proxies are billed per gigabyte of traffic. The rule of thumb: when a few IPs each move a fair amount of data, per-IP pricing wins. When you need many IPs or many locations, per-gigabyte pricing wins.
Which one should you choose? Choose ISP proxies when you need the same IP every day: long sessions, allowlists that only accept a fixed address, and tools that should always connect from one place. Choose residential proxies for scraping and monitoring at scale, many locations, city-level targeting, or frequent rotation. And before you commit, test both on your real targets. Count clean responses, blocks and CAPTCHAs. That number matters more than any label.
Try it yourself. ProxyEmpire's $1.97 trial covers residential and mobile: 100 megabytes of residential and 50 megabytes of mobile data, and it doesn't expire. There's no trial for ISP proxies, but you can start with a single IP. The links are in the description. Thanks for watching.

What Is an ISP Proxy?
A residential-looking IP on server hardwareAn ISP proxy is an IP address that belongs to a consumer internet service provider but is hosted on a server rather than in someone’s home. Every block of IP addresses on the internet is registered to an organisation and announced under an autonomous system number (ASN), the identifier that tells the rest of the internet which network an address belongs to. When a proxy provider leases addresses from a broadband or telecom company and runs them from well-connected servers, websites see a consumer provider’s ASN, the same kind of network a home user would come from, while you get server-grade speed and uptime.
That combination is why the product became popular, first with people managing online store and marketplace accounts, then with everyone who needs a stable identity. The IP is yours alone for the rental period, it does not change between sessions, and it does not disappear because somebody switched off their router. The industry used the name “static residential proxy” first; “ISP proxy” became the more common label later. At ProxyEmpire they are the same product, and you will see both names on our site.
The trade-offs follow from the same design. Addresses have to be leased from a limited number of providers in a limited number of places, so the pool is much smaller than a residential network, locations are usually limited to countries and major cities, and every IP you want costs money whether you use it heavily or not. ProxyEmpire sells ISP proxies in 24 countries: the United States, Canada, the United Kingdom, Germany, France, Spain, Italy, the Netherlands, Belgium, Austria, Poland, the Czech Republic, Romania, Brazil, Japan, South Korea, Hong Kong, Singapore, Australia, Switzerland, Israel, India, Turkey and Ukraine.
What Is a Residential Proxy?
Real household connections, shared as a poolA residential proxy routes your request through a real device on a home internet connection: a computer, phone or router whose owner has agreed to share spare bandwidth. The exit IP is the household’s own address, assigned by its ISP, so it looks exactly like an ordinary visitor because it is one. Providers build networks of millions of these connections and put a single gateway in front of them. You connect to the gateway, and it picks an exit IP for you based on the location and session settings in your username. Our P2P proxy guide explains how these peer networks are built.
Two behaviours matter. With rotation, each new request or connection can leave from a different IP, which spreads a large job across many addresses. With a sticky session, you keep one IP for a series of requests; at ProxyEmpire there is no fixed time limit, and the IP stays until you rotate it or the device behind it goes offline. Because the network covers real homes almost everywhere, you can target not only a country but a region, city, ZIP code, ISP or ASN, all at no extra charge. Our guide to what residential proxies are covers sourcing and ethics in more depth.
The limits are the mirror image of ISP proxies: you cannot guarantee the same IP next week, speed depends on the household’s connection, and heavy data use gets expensive because you pay for every gigabyte.
Seven Key Differences Between ISP and Residential Proxies
What actually changes in day-to-day use1. IP stability
This is the deciding difference for most buyers. An ISP proxy keeps the same address day after day, which is what a site expects from a returning customer logging in to the same account. A residential sticky session can hold an IP for a long time, but it cannot promise that the same address will be available tomorrow, because the device behind it belongs to someone else.
2. Pool size and diversity
A residential network gives you access to millions of IPs across thousands of cities and providers. With ISP proxies you have exactly the IPs you bought. For a job that needs thousands of different addresses, such as checking prices on a large retailer every hour, only a residential pool is practical.
3. Location targeting
ISP proxies are sold per country. Residential proxies target down to city and ZIP level, and also by ISP and ASN, which matters for local search results, delivery-area pricing and ads that differ from one town to the next.
4. Speed and reliability
Server hardware and data-centre connectivity make ISP proxies consistently fast with very low latency. Residential speeds are good for browsing and scraping but vary with each household’s upload speed and distance from the gateway. For long file downloads or time-sensitive checkout flows, the consistency of an ISP IP is noticeable.
5. How sites see them
Both show a consumer ISP’s ASN, which is why both pass checks that immediately flag hosting IPs. Sophisticated anti-bot systems also look at other signals, such as how an IP behaves over time and whether its network characteristics match a home connection, and a genuine household IP is the hardest thing to argue with. In practice, well-managed ISP IPs work on the vast majority of sites, and residential IPs are the fallback for the strictest ones. Neither makes up for bot-like behaviour.
6. Pricing model
ISP proxies cost a flat fee per IP per month, whatever you do with them. Residential proxies cost per GB, whatever number of IPs you touch. That single difference often decides the choice on its own, and the next section puts numbers on it.
7. Protocols and setup
There is no difference here. Both work with HTTP, HTTPS and SOCKS5, both use a username and password, and both plug into the same tools: browsers, anti-detect browsers, scrapers and bots. Switching between them later is a matter of changing the host, port and credentials.
Per IP or Per GB: What ISP and Residential Proxies Cost
Work out your traffic firstProxyEmpire prices ISP proxies from $3.50 down to $2.00 per IP per month depending on how many you buy, with no separate bandwidth to purchase. Rotating residential proxies start at $3.50 per GB pay-as-you-go and fall to $1.50 per GB on larger plans, with more than 30 million IPs included. Two quick examples show how that plays out:
| Scenario | ISP proxies | Residential proxies |
|---|---|---|
| 10 marketplace accounts, each logged in daily from its own IP, about 3 GB per account per month | 10 IPs × $3.50 = $35/month | 30 GB × $3.50 = $105/month, and no guaranteed fixed IP |
| Price checks on 50,000 product pages a day across 20 cities, about 200 GB per month | Would need hundreds of IPs in cities ISP proxies cannot target | 200 GB at a volume rate, thousands of IPs in every city |
The rule of thumb: when you need a few IPs that each move a moderate amount of data, per-IP pricing wins; when you need many IPs or many locations, per-GB pricing wins. If your workload needs both a residential pool and heavy traffic, look at unlimited residential proxies, which remove the per-GB meter. Current plans are on the pricing page.
Key takeaways
- ISP proxies are fixed IPs from consumer ISPs, hosted on servers: fast, stable and priced per IP.
- Residential proxies are real household IPs from a large pool: many locations, rotation, priced per GB.
- Pick ISP for a few long-lived identities; pick residential for scale, rotation and city-level targeting.
- Both use the same protocols and credentials, so you can run them side by side.
ISP or Residential Proxies: Which to Choose for Your Job
Recommendations for common use cases| Use case | Choose | Why |
|---|---|---|
| Managing social media or seller accounts | ISP | One consistent IP per account, every day |
| Access to tools that allowlist your IP | ISP | The address never changes, so the allowlist stays valid |
| Long logged-in sessions and dashboards | ISP | No mid-session IP changes |
| Web scraping at scale | Residential | Rotation across millions of IPs spreads the load |
| SEO rank tracking and local search | Residential | City and ZIP targeting shows real local results |
| Price and stock monitoring | Residential | Many locations and high request volume |
| Ad verification | Residential | See ads the way users in each city see them |
| Sneaker and limited-release checkouts | Both | ISP for speed on the drop, residential for scale |
Many teams end up using both. A typical setup keeps a handful of ISP IPs for the accounts that must look the same every day, and a residential plan for research, monitoring and anything that benefits from rotation. Because both products share the same dashboard and support team, running them together adds no extra work.
If the job depends on mobile networks, for example testing how an app or site behaves for 4G and 5G users or managing accounts that are normally used on phones, neither is ideal; mobile proxies come from real carrier connections and are the better fit.
How to Test ISP and Residential Proxies Before You Commit
Measure on your own targets- Check the network behind the IP. Look the exit IP up in a public IP lookup and confirm the organisation and ASN are a consumer provider, not a hosting company.
- Measure success rate on your real targets. Run a few hundred requests to the sites you care about and count clean responses, blocks and CAPTCHAs. This number matters more than any label.
- Measure speed where it matters. Time full page loads, not just a ping. ISP proxies should be consistently fast; residential results will spread more widely.
- Check stability over days. For ISP IPs, confirm the address and its reputation stay the same across a week of use.
- Estimate your traffic. Log how many GB a typical day uses, then compare the per-IP and per-GB costs with the table above.
ProxyEmpire’s $1.97 trial includes 100 MB of residential and 50 MB of mobile bandwidth, enough to run the first three checks on your own targets. Our support team, available 24/7 and staffed by real people, can help you size an ISP order once you know how many identities you need.
ProxyEmpire proxies are for lawful use. Some site categories, such as banking, payment and government websites, are blocked by default on all products.
ISP vs Residential Proxies FAQ
Straight answersWhat is the difference between ISP and residential proxies?
An ISP proxy is one fixed IP registered to a consumer ISP and hosted on a server, rented per IP. A residential proxy is access to a pool of real household IPs, rotated or sticky, paid per GB.
Are ISP proxies the same as static residential proxies?
Yes. The two names describe the same product, and ProxyEmpire uses both.
Are ISP proxies better than residential proxies?
Neither is better overall. ISP proxies are better for a few stable identities and long sessions; residential proxies are better for scale, rotation and precise location targeting.
Do ISP proxies rotate?
No. You keep the same IP for the rental period. If you need a new IP, buy another one or use a rotating residential plan.
Which is faster, ISP or residential proxies?
ISP proxies, usually. They run on servers with data-centre connectivity, while residential speed depends on each household’s connection.
Can websites tell an ISP proxy from a home connection?
Both show a consumer ISP’s network, so simple checks cannot. Advanced systems look at behaviour and other signals, which is why residential IPs remain the fallback for the strictest sites.
In which countries are ProxyEmpire ISP proxies available?
In 24 countries, including the United States, the United Kingdom, Germany, France, Canada, Japan and Australia. Residential proxies cover more than 170 locations.
