Using this network with a proxy

It targets that one network, and it is not applied on geo-forced pools. If no exit on the network is available, the request fails instead of falling back to another network. We do not publish which networks are available at a given time.

A request names it with the asn option, written AS21928 or 21928. Every pool takes it: Essential and Premium Residential, and Mobile.

Essential and Premium
