ISP proxies = datacenter speed + residential trust + stable IP. Residential = rotation + scale. Here's how to pick.

Architecture

ISP: datacenter-hosted, ISP-registered ASN, no rotation. Residential: routed through actual peer devices on ISP networks, rotating exit IPs.

ISP charges per IP per month (unlimited bandwidth). Residential charges per GB (any IPs).

Sticky session workloads — sneakers, social media, account management. High-bandwidth on a small IP fleet. Predictable monthly cost.

Massive IP rotation at scale (millions of unique exits/day). Geo coverage in long-tail countries. Mobile-like trust without mobile prices.

At ~100GB/month per IP, ISP is cheaper than residential. Below that, residential wins.
