ISP vs Residential vs Mobile Proxies Explained
By froxproxy Team · June 10, 2026 · 2 min read
“Residential-grade” proxies come in three flavours, and they aren’t interchangeable. Here’s how ISP, residential, and mobile proxies compare — and when each is the right call.
Quick definitions
- ISP proxies: static IPs issued by an ISP but hosted on datacenter hardware. Residential trust, datacenter speed, and the IP never rotates.
- Residential proxies: a large rotating pool of real home IPs, billed per GB. Maximum coverage and stealth.
- Mobile proxies: IPs from 4G/5G carrier networks, shared by thousands of real subscribers — the hardest to block.
Comparison
| Factor | ISP | Residential | Mobile |
|---|---|---|---|
| IP stability | Static | Rotating/sticky | Rotating |
| Trust level | High | High | Highest |
| Speed | Very fast | Fast | Moderate |
| Bandwidth | Unlimited | Per GB | Unlimited |
| Cost | Low per proxy | Per GB | Highest |
Choose ISP proxies when…
You need a fast, stable IP that stays the same for long sessions — account management, marketplace automation, or high-speed scraping where unlimited bandwidth keeps costs flat. See ISP proxies.
Choose residential proxies when…
You need broad geographic coverage and rotation across a huge pool — large-scale scraping, ad verification, and price monitoring. See residential proxies.
Choose mobile proxies when…
You’re working against the most aggressive detection — social media platforms especially. Because a single mobile IP is shared by thousands of real users, blocking it isn’t practical for the target. See mobile proxies.
Bottom line
- Stability and speed → ISP
- Coverage and scale → residential
- Maximum stealth → mobile
