Datacenter vs residential proxies: what separates cheap server IPs from real home IPs, how each gets flagged, what they really cost, and which one to use.

How websites detect proxies: the detection stack from the defender's seat, ASN and IP reputation, TLS and HTTP/2 fingerprints, headers, behavior, and leaks.

What is a residential proxy? A real home IP that makes your traffic look like an ordinary person online. How it works, why sites trust it, and what it costs.
