ASN and carrier targeting

Pin traffic to a specific network operator.

An autonomous system number identifies the network an address belongs to — Comcast, Deutsche Telekom, Vodafone. Targeting one is the strongest signal available when a target profiles connections by network origin rather than by geography.

Mobile carriers

On the mobile network, carriers have friendly slugs as well as ASNs, because the mapping between a mobile operator and its autonomous systems is rarely one to one.

Narrow pools rotate less

Combining country, city and ASN can reduce the eligible pool to a few thousand addresses. That is fine for low volume and counterproductive at high volume, because you will revisit the same exits often enough to look unusual. Drop the narrowest flag first when success rates fall.
