Residential Proxy
A residential proxy routes traffic through an IP address assigned by an ISP to a real household, making the traffic appear to come from a genuine home internet connection.
What is a Residential Proxy?
A residential proxy forwards internet requests through an IP address that belongs to a real Internet Service Provider (ISP) and is assigned to a physical household. This stands in contrast to datacenter proxies, which use IPs from cloud hosting or colocation facilities. Because residential IPs appear on the same networks as ordinary consumers, traffic routed through them is significantly harder to distinguish from genuine user activity.
How Residential Proxy Networks Operate
Large-scale residential proxy providers maintain pools of millions of IPs, often sourced through SDK integrations in free mobile apps or browser extensions. Users of these apps may not fully realize their device is being used as a relay. Providers then sell access to these IPs to customers who want to appear as real users in specific geographic locations. Many operate as backconnect proxies, automatically rotating the exit IP on each request.
Why Residential Proxies Are a Threat
Residential proxies are the tool of choice for sophisticated bot operators. They enable web scraping that bypasses rate limits, credential stuffing that evades IP-based blocking, and multi-accounting that appears to originate from different households. Traditional IP blocklists are largely ineffective because the IPs belong to real ISPs and may also carry legitimate traffic.
Detecting Residential Proxies
Identifying residential proxy usage requires advanced threat intelligence. AntiProxies combines network topology analysis, traffic pattern recognition, and proprietary data feeds to flag IPs that are part of known residential proxy networks, even when those IPs would pass a simple ASN or geolocation check. Pairing this with device fingerprinting gives platforms a layered defense against these stealthy threats.
