Proxy Check

Determine whether an IP address belongs to proxy infrastructure or a normal access network.

What this checks

  • Explicit proxy, proxy type, Tor, residential proxy, privacy relay, and VPN traits.
  • Datacenter, cloud, mobile, ASN, operator, usage type, and classification confidence.
  • Evidence signals that explain why the IP was flagged as proxy-like or normal.

How to interpret results

  • Proxy likely means an explicit proxy, Tor, residential proxy, or proxy-type signal was returned.
  • Proxy possible means VPN, relay, datacenter, cloud, or hosting signals need context.
  • No proxy evidence means the current data did not flag proxy-like traits, not that a proxy is impossible.

Common issues

  • Corporate gateways, cloud networks, VPN exits, and privacy relays can share proxy-like traits.
  • Residential proxy labels can be more sensitive than normal residential ISP labels and should be reviewed carefully.

Privacy note

The proxy check uses first-party IP intelligence data and does not run an active proxy connection test against the IP.

Frequently Asked Questions

How does the proxy check decide whether an IP is a proxy?

The proxy check reads classification signals such as proxy, proxy type, Tor, VPN, privacy relay, residential proxy, datacenter, cloud, and confidence.

Can a datacenter IP be a normal non-proxy IP?

Yes. Datacenter or cloud ownership is context, not proof of an open proxy. The result should be read with proxy type, confidence, ASN, and evidence signals.
