The short answer
Residential proxy networks need real home connections. One common way to get them: an app or SDK that asks people to share some of their unused bandwidth, in return for money, credits, or an ad-free version of another app. While it runs, proxy customers' requests exit through that home IP.
What good looks like
Clear opt-in consent, an obvious way to stop, limits on what traffic is allowed, and payment or a fair trade. The opposite, devices enrolled by malware without consent, has been the target of law-enforcement takedowns.

Also known as
Proxyware, passive income app, peer SDK, residential proxy SDK.
