Residential Flex now matches the exit's OS fingerprint (p0f)
Most residential pools are mostly Linux-based devices: phones, routers,TV boxes. A Windows browser profile that goes out through such an exit shows a Windows user-agent on top of a Linux TCP stack, and that mismatch is exactly what passive fingerprinting (p0f and the engines built on the same idea) is designed to catch. The rebuilt Residential Flex lets you choose the exit by its OS fingerprint: Windows machines, or Linux-based devices (Android, macOS, Linux).
How you use it: one option in the login, os-windows or os-android, on top of any geo. Windows exits are a part of the pool and the share varies by country, so expect fewer exits with the filter on.
Everything else that changed in Flex
- Targeting: country, state or region, city, ISP (ASN) and US ZIP code. City is exact for large metro areas, US ZIP is exact where inventory exists; outside the US a postal code narrows to the city.
- Fallback mode. By default a target with no live exit fails instead of handing you an address somewhere else; the country is never swapped. With fallback on, the gateway loosens ASN, then ZIP, city and region, staying inside the country.
- Sticky sessions up to 120 minutes by session id, held across all the parallel connections a browser opens. Send the first request alone, then start the parallel load.
- Speed mode for sticky sessions: the session starts on the fastest of several exits tried. Keep it low (1-3) for account work.
What is gone: UDP (Flex is TCP only; Residential Turbo has UDP built in), exclusion filters, and the 2:1 traffic rate on advanced filters.
