What Is a Residential Proxy?

A residential proxy is a proxy server that routes your internet traffic through an IP address assigned by an Internet Service Provider (ISP) to a real residential device, making your requests appear as genuine consumer traffic.

Understand how residential proxies work, the different types available, and why they are the gold standard for web scraping, ad verification, and accessing geo-restricted content.

Explained

A residential proxy acts as an intermediary between your device and the website you want to access. Unlike datacenter proxies, which use IPs from cloud hosting providers, residential proxies use IP addresses that belong to real households. These IPs are assigned by ISPs such as Comcast, AT&T, or Vodafone to actual homeowners, which means websites see your requests as coming from a legitimate residential user.

This distinction matters because most anti-bot systems and website security tools maintain databases of known datacenter IP ranges. When a request arrives from a datacenter IP, the website can quickly flag it as non-human traffic. Residential IPs, on the other hand, are indistinguishable from regular visitors browsing from their home network.

Residential proxies have become the standard for any task that requires high anonymity and low detection rates. They are widely used in web scraping, price monitoring, ad verification, market research, and accessing content that is restricted to specific geographic regions.

How It Works

When you send a request through a residential proxy, your traffic is first routed to the proxy provider's gateway server. The gateway selects an available residential IP from the provider's pool and forwards your request through that IP to the target website. The website receives the request, sees the residential IP address, and responds as it would to any normal visitor. The response is then sent back through the proxy to you.

Residential proxy providers maintain large pools of IPs by partnering with applications and services that users opt into, allowing their idle bandwidth and IP address to be used as proxy endpoints. Providers like Shifter maintain pools of hundreds of millions of residential IPs across hundreds of countries and cities, enabling users to target specific geographic locations and rotate IPs automatically to avoid detection.

Types

Residential Proxies

Residential proxies automatically assign a new IP address from the pool for each request or at set time intervals. They are ideal for large-scale web scraping where you need to distribute thousands of requests across many different IPs to avoid rate limits and blocks.

Static (Sticky) Residential Proxies

Static residential proxies, also called sticky sessions, maintain the same IP address for a defined period of time (e.g., 5, 10, or 30 minutes). They are useful for tasks that require session persistence, such as logging into accounts, navigating multi-page checkout flows, or scraping paginated results.

Mobile Residential Proxies

Mobile residential proxies route traffic through IP addresses assigned by mobile carriers (3G, 4G, 5G) to smartphones and tablets. These IPs carry an extremely high trust level because mobile carriers use CGNAT, meaning many users share the same IP. They are the hardest proxy type for websites to block.

FAQ

Frequently asked FAQ questions

Common questions about residential proxy.

A residential proxy uses an IP address assigned by an ISP to a real home, while a datacenter proxy uses an IP from a cloud hosting provider. Residential proxies are harder to detect and block because they appear as regular consumer traffic, whereas datacenter IPs can be identified and filtered by anti-bot systems.
