Datacenter and Residential Proxy IPs
Understand what these proxy labels describe, what an ASN lookup can show, and what a free IP list cannot establish.
An ASN or country lookup cannot prove that a proxy runs in somebody's home. “Residential” usually describes an exit associated with a consumer-access network; “datacenter” usually describes one associated with hosting. Those labels do not identify the software listening on the port.
An ASN lookup identifies an autonomous system—a group of networks under a common routing policy. Registration and owner details give network context, not a physical inspection of the endpoint. IP intelligence providers add their own hosting, proxy and other classifications. These are more useful than guessing from a company name, but remain assessments with a source and update history.
Before relying on the label, ask whether it classifies the observed exit itself or only a wider range. Also establish who operates the endpoint, how access is authorized and whether requests can leave through other addresses. A row in a free proxy list containing IP, port, country and an anonymity label does not supply that evidence.
Select the actual HTTP or SOCKS protocol your application supports and verify the connection you need. Residential does not establish credential safety or website acceptance; datacenter does not establish that the endpoint is unusable. Neither label grants permission to operate or use it.
