Ad fraud, geo-misdelivery and brand-unsafe placements are only visible from a genuine consumer IP in the target market — the one thing fraudsters cloak against.
Cloaking defeats datacenter checks
Fraudulent networks detect datacenter ASNs and serve a clean creative. Verification from residential and mobile IPs is the only way to observe the ad a real user is served.
Breadth of geography matters more than volume
You need many countries, cities and carriers rather than huge bandwidth. Prioritise providers with deep ASN and city coverage over headline pool size.
Mobile carrier verification
In-app and mobile-web inventory is targeted by carrier. Verifying it requires real 4G/5G exits on the specific operator, not a residential IP on fixed broadband.

Static Residential Proxies
Static residential proxies (also sold as ISP proxies) give you a fixed IP registered to a consumer ISP but hosted in a datacenter — residential trust with server-grade speed and uptime.
