Definition
A residential IP is an IP address allocated by an ISP to a home internet subscriber. Geolocation databases mark these addresses as residential rather than commercial, and websites that filter for legitimate user traffic treat them differently from data center IPs. Most VPN servers, however, run in data centers, and their IPs are correspondingly classified — making it easier for streaming services and anti-fraud systems to identify and block them.
Why VPNs Want Them
A streaming service that aggressively blocks data center IPs (Netflix, Hulu, BBC iPlayer historically) leaves residential ranges alone, because doing otherwise would harm legitimate paying customers. A VPN that can offer residential exit IPs therefore appears more like an ordinary user. Several specialty providers offer residential proxy networks (often built from peer-to-peer SDK arrangements with consumer apps), and a handful of mainstream VPNs offer dedicated residential IPs as a paid add-on.
Ethical and Reliability Concerns
Residential proxy networks have a fraught reputation. Some are built on networks of users who knowingly opted in (for example, in exchange for free services); others have been built on SDKs bundled into apps without clear disclosure. The reliability of residential exits is also lower because consumer connections are slower, less stable, and have variable uptime compared with data center servers.
