IP REPUTATION CHECKER

IP Address Lookup & Risk Checker

Look up an IP address, understand its location and network, and review risk signals before you trust the connection.

Look up an IP address

We will check the address against current risk, network, location, and attack-history signals.

IP address lookup guide

Find more than an IP address

PreProx brings the most useful parts of an IP lookup into one quick check. Review where an address is registered, which network operates it, and whether the returned signals suggest a proxy, VPN, Tor exit node, datacenter, or residential connection.

Use the result to troubleshoot access, review a new connection, or decide what needs a closer look without exposing your lookup workflow to another service.

IP address finder for location and network details

An IP address finder can return a country, state or region, city, timezone, ISP, organization, and ASN. These details describe the address block and network relationship reported by the lookup source. City-level results are approximate, so they should not be read as an exact device location.

IP quality score, reputation check, and IP score

An IP quality score gives you a fast way to compare returned conditions, while an IP reputation check highlights whether the address carries elevated risk signals. A low risk score is encouraging, but it cannot guarantee delivery, login, scraping, or payment success on a particular service.

IP fraud score and abuse history

Fraud score and attack-history signals can help explain why a connection receives extra review. They are indicators, not accusations. Check the event window, network type, and current context before blocking an address or making an account decision.

Proxy, VPN, Tor, datacenter, and residential signals

Different connection types leave different network patterns. Proxy and VPN flags can help explain shared or masked traffic; Tor and datacenter signals add more context; a residential proxy flag indicates that the address may be associated with a residential access network. Availability depends on the data returned for the address.

Understand the result

How does IP geolocation work?

IP geolocation maps an address to a known network allocation and geographic database. The result can be useful for a broad country or regional view, but internet routing, mobile networks, VPNs, proxies, and database updates can make the city or ISP look different from what you expect.

That is why a good IP address lookup shows the source details beside the score. You can see the location, ASN, provider, connection type, and reputation signals together instead of relying on a single number.

Use scores as context No single lookup can certify that an address is safe, malicious, trustworthy, or tied to a specific person.

Common questions

IP lookup questions answered

What is an IP address lookup?

An IP address lookup connects a public IPv4 or IPv6 address with available network and geolocation signals, such as its country, region, city, ISP, organization, and ASN. It can also return reputation and abuse indicators when those signals are available.

Can I check an IPv4 or IPv6 address?

Yes. Enter a valid public IPv4 or IPv6 address, or leave the field blank to check the public IP detected for your current connection. Private local addresses are not useful for a public reputation lookup.

What is an IP quality score?

The IP quality score is a simple 0–100 estimate derived from the returned risk level, where a lower risk signal produces a higher quality estimate. It is a practical comparison aid, not a guarantee that an address will work for every website or service.

Is an IP fraud score the same as an IP risk score?

They are related but not identical. An IP risk score summarizes signals associated with an address, while a fraud score is usually used in a specific abuse, payment, or account-protection context. Treat either score as one signal in a wider review.

Can an IP lookup identify a person?

No. An IP lookup can describe network and approximate geographic information, but it does not prove who is using the address or reveal an exact physical location. Do not use an IP result as a substitute for identity verification or legal process.
