Residential proxies route through IP addresses that ISPs assign to real homes, so requests look like normal household traffic and get served on strict e-commerce, social, travel and SEO platforms. Datacenter proxies come from cloud servers instead: they are faster and cost less per request, but sites can identify datacenter ranges more easily, so they suit high-volume access to public APIs and sites that don't fight automated traffic. ColdProxy offers both — Residential IPv4 across 195+ countries (GB-based or unmetered speed-tier billing), USA Residential IPv6, and Datacenter IPv6 across 45+ supported locations. As a rule, choose residential when trust and geo-targeting matter most, and datacenter when speed, scale and lower cost matter more than residential reputation. Both support HTTP, HTTPS, and SOCKS5 with sticky or rotating sessions.
