Residential proxies are intermediary servers that use IP addresses assigned by Internet Service Providers (ISPs) to real residential devices, making them appear as genuine users when accessing the internet. These proxies offer anonymity, access to geo-restricted content, and IP rotation to avoid detection by anti-bot measures, making them ideal for web scraping, ad verification, price monitoring, and online marketing. Residential proxies can be rotating, where the IP changes periodically, or static, maintaining the same IP for stability, though static proxies are more expensive due to the need for partnerships with ISPs. Popular use cases include purchasing limited sneakers and tickets, social media management, and SEO monitoring. The best residential proxies are evaluated based on IP count, location, geo-targeting options, protocols, uptime, and user reviews, with Bright Data being highlighted as a leading provider due to its extensive and reliable proxy network.
