Datacenter Proxy

A datacenter proxy uses an IP address assigned to a cloud provider, hosting company, or other datacenter network. Its exit address comes from server infrastructure rather than a household or mobile internet connection.

Datacenter proxies are often fast and inexpensive because providers can operate many virtual or physical servers on high-capacity links. Their addresses are also easier for destinations to classify. Public routing records show the autonomous system that announces an IP range, and hosting ranges often contain many proxy or automated clients. A site may apply different limits or checks to traffic from those ranges.

Residential and mobile proxy categories use exits associated with consumer internet access or carrier networks. That classification can resemble ordinary user traffic more closely, but the IP type alone does not determine whether a request succeeds. Request volume, behavior, headers, cookies, and protocol fingerprints can all affect how a destination handles a client.

An ISP proxy is a middle category: the address is registered to a consumer internet provider but generally hosted on stable server infrastructure. Residential proxies versus datacenter proxies covers the practical differences.
