Scraping at scale is a success-rate problem, not a bandwidth problem. The right pool, rotation strategy and fingerprint alignment beat raw IP count every time.
Match IP type to target difficulty
Send soft targets to datacenter proxies at a tenth of the cost, and reserve residential for the endpoints that actually block you. A tiered router in front of your crawler typically cuts proxy spend by 60–80%.
Fingerprints beyond the IP
Cloudflare, DataDome, PerimeterX and Kasada score TLS (JA3/JA4), HTTP/2 frame order, and JS runtime signals. A perfect residential IP with a Python-requests TLS fingerprint still gets a 403.
Rotation and session strategy
Rotate per request only for stateless endpoints. For paginated or authenticated flows, hold a sticky session and retire the IP once it starts returning challenges.
Measure the right metric
Track successful parsed records per dollar, not requests per second. A cheap pool with a 40% block rate and three retries costs more than a premium pool at 97%.

Residential Proxies
Residential proxies route your traffic through real household IP addresses handed out by consumer ISPs, so target sites see an ordinary broadband customer instead of a server.

Rotating Residential Proxies
Rotating residential proxies assign a different household IP to each request (or each short interval), spreading a crawl across thousands of ISPs so no single address ever trips a rate limit.

Static Residential Proxies
Static residential proxies (also sold as ISP proxies) give you a fixed IP registered to a consumer ISP but hosted in a datacenter — residential trust with server-grade speed and uptime.
