What Are Residential Proxies? Best Proxies for Web Scraping
A residential proxy routes your web requests through a real residential IP address assigned by an ISP to a home user. Because the IP belongs to a real device and location, websites are far less likely to block it compared to datacenter IPs.
Residential vs. Datacenter Proxies
| Feature | Datacenter | Residential |
|---|---|---|
| IP source | Cloud servers | Real homes/devices |
| Detection risk | High | Low |
| Speed | Very fast | Moderate |
| Cost | $1-5/GB | $5-15/GB |
| Best for | Unprotected sites | Anti-bot protected sites |
How Residential Proxies Work
Proxy providers build networks of residential IPs through:
- •Mobile SDK partnerships (apps that opt users into sharing bandwidth)
- •ISP partnerships
- •Peer-to-peer networks
When You Need Residential Proxies
- •Scraping sites with anti-bot protection (Cloudflare, DataDome)
- •Targeting location-specific content
- •Maintaining long sessions (login required scraping)
- •When datacenter proxies keep getting blocked
When Datacenter Proxies Are Fine
- •Scraping sites without anti-bot protection
- •Public data APIs
- •Government or academic sites
- •High-volume scraping of permissive sites
Choosing a Provider
Key factors:
- •Pool size: More IPs = less chance of bans (look for 10M+)
- •Geographic coverage: Can you target specific countries/cities?
- •Rotation options: Automatic rotation vs. sticky sessions
- •Pricing model: Per GB vs. per request vs. per IP
- •Speed and uptime: Test before committing
Cost Optimization
Residential proxies are expensive. Save bandwidth by:
- •Blocking images and CSS in headless browsers
- •Caching responses you've already fetched
- •Using datacenter proxies for the easy sites, residential only for hard targets
- •Compressing requests where possible
