IP Address Lookup and Geolocation Tool

Enter any IPv4 or IPv6 address, or leave the field empty to check your own, and see where it appears to be located, who runs the network and which time zone it uses.

What the lookup shows

The tool returns the fields that websites most often use to decide how to treat a visitor. The country and region say where the address is registered or routed. The city is a best guess. The ISP or organization names who operates the network, and the ASN (autonomous system number) identifies that network in routing tables. The time zone shows the zone attached to the location, which is worth comparing with your browser's own.

  • Country and region: the main basis for localized prices and content.
  • City: an estimate, often the provider's hub, not a street address.
  • ISP and ASN: whether the address belongs to a home provider, a mobile carrier or a hosting company.
  • Time zone: should be consistent with the location.

How to read the result

Start with the network owner. A home or mobile carrier name suggests a consumer line, while a cloud or hosting company suggests a datacenter address, which many sites treat more cautiously. Then compare the country with what you expect. IP geolocation is built from registry data, routing data and commercial databases, so providers disagree sometimes, and the same address can resolve to neighboring cities in two tools. A one-city mismatch is normal; a different country is a real problem.

Why it matters if you use a proxy

When you buy a proxy for a specific market, the lookup is the quickest way to confirm the exit matches your targeting. Run it through the proxy and check three things: the country is the one you asked for with a token such as -country-de, the city or ISP matches any narrower targeting, and the network type fits the product you bought. Residential proxies should show a consumer ISP; datacenter proxies will show a hosting network, which is expected.

Note that a proxy can sit in front of a lookup page that is requested by your browser: if you open this page in a browser that is not using the proxy, you will see your own address instead. For a scripted check, send the request to a lookup service through the proxy.

Fixing a mismatched or unexpected result

  • Wrong country: recheck the targeting tokens in your username and confirm the proxy line is applied to the browser or script that you are testing.
  • Right country, wrong city: city data is approximate. If city matters, test several sessions and judge by the majority.
  • Your own IP appears instead of the proxy: the app is bypassing the proxy. Check system proxy settings and see the WebRTC leak test.
  • Address flagged as hosting: you may be on a datacenter line; switch to residential if you need a home profile.

Privacy

The lookup reads public geolocation data for the address you enter and sends the result to your browser. See also the IP reputation check and what is my IP.

Frequently asked questions

Country-level results are usually reliable, while region and city are estimates built from registry, routing and commercial data. Providers can disagree by a city, and mobile or business lines are the least precise.
