ASN Targeting

Our Residential Proxies support targeting by ASN number which means that you can choose proxies from specific carriers. You have to enter the required ASN number in your request. Below is the example for AT&T Corp., its ASN number in the US being 6389:

curl -x a5bb901cab290ae4.wpu.as.pyproxy.io:16666 -U "USERNAME-zone-resi-region-us-asn-AS6389:PASSWORD" ipinfo.pyproxy.io

You can find ASN numbers here

Residential Proxies pool is dynamic in its nature so if there are no IPs under that specific ASN at that moment, you will receive error response. In such case, you should try another ASN number.

You can use either Country or ASN parameter per each request. If both location parameters are used, only Country parameter will be applied.
