About this tool

Not every IP address is a home broadband line. Many belong to datacentres, cloud hosting providers, public proxies, VPN services or Tor exit nodes — and telling those apart from a residential ISP is often exactly what you need to know when reviewing traffic. This tool analyses the routing characteristics of an address to indicate whether it looks like a genuine consumer connection or a commercial hosting, proxy or VPN route.

The signals come from how the address is allocated and routed: hosting and VPN providers announce their ranges differently from residential ISPs, and known proxy and Tor infrastructure is identifiable. Sites use the same kind of analysis for fraud checks, abuse prevention and content licensing, which is why a VPN sometimes triggers extra verification. Seeing the classification helps you understand why an address might be treated as higher-risk.

No detection of this kind is perfect. Residential proxies and freshly provisioned servers can blur the line, so treat the result as a strong indicator rather than a verdict. Combine it with the IP lookup here for the provider and location behind an address, and with your own logs for context.

Frequently asked questions

How does this tell a VPN apart from a home connection?
It examines how an address is allocated and routed. Datacentres, hosting providers and VPN services announce their address ranges differently from residential ISPs, and known proxy and Tor infrastructure can be recognised from that footprint.
Why do some sites block or challenge VPN and proxy IPs?
Because addresses associated with hosting, proxies and VPNs are more often linked to fraud, scraping or abuse, and because content licensing sometimes requires location checks. Sites use detection like this to decide when to add verification.
Is the result always correct?
No detection is perfect. Residential proxies and new servers can be misclassified in either direction, so treat the outcome as a strong indicator and corroborate it with other information when it matters.
What is a Tor exit node?
It is the last relay in the Tor network, whose IP address is what destination sites actually see. Because the list of exit nodes is public, traffic from them is easy to identify and is often treated with extra caution.
Can I check the location behind the address too?
Yes — use the IP lookup tool on this site to see the country, provider and ASN for an address alongside this proxy and VPN classification.
