Two kinds of "residential"
Both ISP proxies and residential proxies give websites an IP registered to a consumer internet provider. That's where the similarity ends.
- ISP proxies are hosted on servers in data centres. The IPs are static, fast and always online. You rent specific IPs.
- Residential proxies run through real consumer devices. The IPs rotate through a pool of millions, are slower and come and go. You buy bandwidth.
Comparison
| ISP proxies | Rotating residential proxies | |
|---|---|---|
| Hosting | Data centre servers | Real home devices |
| IP behaviour | Static, yours until you release it | Rotates per request or session |
| Pool size | Hundreds to thousands | Millions |
| Speed / latency | Fast, low latency | Moderate, variable |
| Uptime | Near 100% | Session can drop |
| Geo-targeting | Limited locations | Country, state, city, ASN |
| Pricing | Per IP (often unlimited data) | Per GB |
| Detectability | Hard, but server-like patterns possible | Very hard |
| Subnet diversity | Low to moderate | Very high |
Where ISP proxies win
- Speed-sensitive tasks like sneaker checkouts. See ISP proxies for sneakers.
- Persistent identities: social accounts, seller accounts, ad accounts that should log in from one place.
- Bandwidth-heavy work on a limited number of IPs, where per-GB pricing would be expensive.
- Long browser sessions that can't tolerate an IP change.
Where residential proxies win
- High-volume scraping across many pages that needs massive IP diversity.
- Precise geo-targeting, such as city-level search results or local ads.
- Avoiding subnet-level bans, because residential IPs are scattered across countless subnets.
- Raffles and unique-IP-per-action tasks.
- Targets that detect server-hosted "residential" IPs. Some advanced systems notice when an ISP-registered IP behaves like a server.
Proxy tip: Geonode is one of the providers that sells all of the main types under one account: rotating and sticky residential, static ISP proxies with unmetered bandwidth, and rotating datacenter proxies. That makes it easy to test which type a target actually needs. More in Geonode ISP proxies.
Cost comparison example
Suppose you run 20 browser sessions all day on a protected site, transferring 50 GB per month in total.
- ISP: 20 IPs at about $2.50 each is $50/month, with unlimited data.
- Residential: 50 GB at about $3/GB is $150/month.
Now suppose you need 1 million lightweight requests spread across thousands of IPs, transferring 20 GB.
- ISP: you'd need hundreds of IPs to spread the load, at hundreds of dollars.
- Residential: 20 GB at about $3/GB is $60.
The shape of your traffic decides. See proxy bandwidth pricing explained.
Using both
Many teams use ISP proxies for logged-in, long-lived identities and rotating residential for bulk data collection. In sneaker setups, ISP proxies handle checkout tasks and residential proxies handle raffle entries and account creation.
Detection: how sites might tell them apart
Both ISP and residential proxies show consumer ISP ASNs. Sophisticated systems may still distinguish them by:
- Network behaviour: server-hosted IPs may have unusually stable uptime, low latency to data centres and server-like TCP/IP characteristics.
- Traffic patterns: a home IP usually carries mixed traffic from many apps; an ISP proxy IP may carry only your traffic.
- IP history databases that flag ranges known to be sold as ISP proxies.
- Subnet patterns: many IPs from the same block behaving similarly.
In practice, ISP proxies still perform very well on most sites. On the very strictest targets, rotating residential or mobile can outperform them.
Session design with each type
ISP: treat each IP as a persistent identity. One account or one long-running task per IP.
Residential: treat each session ID as a temporary identity. Rotate between tasks, and expect occasional mid-session drops.
Budget tip: If you want a cheap proxy to try this with, Webshare has a free plan with 10 datacenter proxies and 1 GB of bandwidth a month, no card required. Paid lists let you pick proxy count, bandwidth and location. See Webshare static residential proxies.
Choosing for browser automation
For headless browsers, bandwidth costs often decide. A full browser session can transfer hundreds of MB per day. On per-GB residential that adds up; on per-IP ISP it's free. If ISP proxies work on your target, they're often the cheaper choice for continuous browser workloads. See headless browser proxies.
A simple decision table
| Your situation | Choose |
|---|---|
| Need the same IP tomorrow | ISP |
| Need thousands of different IPs today | Residential |
| Heavy bandwidth, few IPs | ISP |
| Light bandwidth, many IPs | Residential |
| City-level targeting in many cities | Residential |
| Sneaker checkouts | ISP |
| Sneaker raffles | Residential |
| Strictest anti-bot targets | Test both; consider mobile |

Residential tip: Rayobyte is worth testing when you need precise targeting: its residential proxies can be pinned to a country, state, city, ZIP code or ASN, with sticky sessions from 1 to 120 minutes. More in Rayobyte static ISP proxies.
Moving a workload from residential to ISP
Teams often start on rotating residential and later realise part of their workload would be cheaper and more stable on ISP proxies. A safe way to migrate:
- Find the sticky-heavy jobs. Look for tasks that hold one session for a long time: logged-in work, account management, or monitoring the same pages repeatedly.
- Measure their bandwidth. If a job moves many gigabytes through a handful of sessions, per-IP pricing will usually beat per-GB.
- Count the IPs you need from concurrent sessions, not total sessions per month.
- Match locations. ISP proxies cover major metros well; keep long-tail locations on residential.
- Map each account or task to one IP and record it, so identities don't wander. See static residential proxies.
- Run both side by side for two weeks, then compare cost per successful task and block rates.
- Keep residential for what it does best: wide rotation, rare locations and sudden spikes.
The usual end state is a blend: ISP for persistent identities and heavy repeat traffic, residential for breadth. For buying the ISP side, see best ISP proxies. For browser setups that pin each context to its own IP, see using a different proxy per page in Puppeteer.

FAQ
Are ISP proxies more expensive than residential proxies?
Per IP they cost more than datacenter IPs; whether they're more expensive than residential depends on how much bandwidth you use.
Which is better for Puppeteer?
For long logged-in sessions, ISP. For scraping many pages with fresh IPs, residential with sticky sessions. See Puppeteer proxies.
Can ISP proxies be detected?
Some sophisticated systems can spot server-like behaviour, but ISP proxies still perform very well on most sites.
