Definition
A residential proxy routes internet traffic through an IP address assigned by an internet service provider to a real home connection, rather than through a data-centre IP. Because the address belongs to a genuine consumer ISP range and often to a real device, it is far harder for a website to flag as automated or suspicious than a data-centre IP, and it can be chosen by country, region, city or carrier.
Mobile proxies are a related type that route through carrier-assigned mobile IPs, which rotate naturally and are trusted even more.
Providers build residential pools through SDKs bundled into free apps, browser extensions and "free VPN" products whose users consent - sometimes unknowingly - to share their bandwidth. This raises real questions about how informed that consent is, which is a recurring ethical and legal criticism of the residential-proxy industry.
In context
In iGaming, residential and mobile proxies appear on both sides of the line. Legitimately, operators and networks use them for geo-accurate ad verification (checking what ads and pages users in a specific market actually see), competitor monitoring, price and offer checks, and QA of geo-targeting and localisation.
These are read-only, low-volume, honest uses.
On the grey side, residential proxies are the geo-matching layer of the multi-accounting stack: each anti-detect browser profile gets a residential or mobile IP in the target country so a farmed or rented ad account looks like a local user, defeating the ad platform's IP-based linking and location checks. They are also used to make click traffic appear to originate from a high-value geo it did not, which is a form of traffic fraud that inflates an affiliate's apparent Tier-1 volume.
For an operator reviewing traffic quality, a mismatch between proxy-consistent IP geo and other device or behavioural signals is one of the flags that traffic is not what it claims to be. The proxy itself is a neutral tool; the use determines whether it supports honest verification or geo-spoofing.
Worked example
A network's compliance team uses residential proxies in five markets to verify that affiliates' landing pages show the correct licence details and responsible-gambling messaging to local users. A grey buyer in the same market uses mobile proxies so 30 farmed ad accounts each present a distinct local carrier IP, slowing the platform's ability to link and ban them together.
