Public Route Checker

Find ISP, ASN and Geolocation for a Public IP

Enter any routable IPv4 or IPv6 value to see its approximate location, provider, organization, ASN, and privacy-service likelihood. To inspect your own connection, use the What Is My IP checker.

Check a public value

Results use free public geolocation data and are approximate. Private, loopback, link-local, CGNAT, multicast, and reserved ranges are not publicly routable and cannot be mapped. You can share a report with a URL like /ip-lookup/?ip=8.8.8.8.

What the report shows

This page turns a raw public value into context: the operator behind it, approximate location, ASN, and signals that may indicate a privacy service, proxy, relay, or hosting provider. It is useful for troubleshooting, checking a tunnel exit, preparing allow-lists, and reviewing server-log traffic.

How accurate is it?

Geolocation is not GPS. It is derived from routing and public databases, so results can point to a regional hub, mobile carrier, or tunnel exit rather than a precise place. For background, see What Is an IP Address?

Common use cases

Use this tool to confirm a tunnel exit, check the owner of traffic seen in logs, validate a public value before adding it to an allow-list, compare IPv4 and IPv6 routing, or identify hosting, ISP, business, or mobile-carrier ownership.

Limitations

This report cannot prove a person's identity, exact location, device, or intent. Shared connections, CGNAT, tunnel exits, proxies, and data centers can group many users behind one visible value. Treat the result as routing context and combine it with logs, timestamps, and other security signals.

What this tool checks

The tool checks whether the entry is a routable IPv4 or IPv6 value, then requests geolocation and routing details from public data sources. The result focuses on details useful for troubleshooting: country, city, provider, organization, ASN, time zone, and privacy-service likelihood. Reserved ranges, loopback values, link-local ranges, multicast, and private LAN ranges are rejected because public geolocation does not apply to them.

How the check works

When you submit a value, the page normalizes the input and asks the backend for a report. The backend combines source data and returns a structured result to the browser. Some fields may be missing when public datasets do not have a reliable answer. That is normal for newly assigned ranges, recently moved routes, some enterprise environments, and values used by mobile carriers or cloud platforms.

Troubleshooting results

If a result looks wrong, check whether the value belongs to a privacy service, proxy, hosting provider, or mobile gateway. Those routes often point to a data center or regional hub instead of the user. If the page says the input is not public, confirm that you did not paste a private LAN range such as 192.168.x.x, 10.x.x.x, 172.16-31.x.x, localhost, or an IPv6 link-local value starting with fe80. For live browser context, compare it with the homepage checker.

Related tools

After checking a public value, open ASN Finder to see the wider routing owner and announced prefixes. Use the VPN Guide to understand why a privacy service changes visible details. If you are testing your own browser, use the WebRTC leak test and IPv6 test to compare browser exposure with the public result.

Frequently asked questions

Can I check any public value?

You can check routable IPv4 and IPv6 values. Private, loopback, link-local, CGNAT, multicast, and reserved ranges cannot be geolocated publicly because they are not reachable on the open internet.

How accurate are the results?

Results are approximate. Free public geolocation data may point to the provider's regional hub, a mobile carrier, or a privacy-service exit rather than an exact location.

Why does the result show a data center?

The value may belong to a privacy service, proxy, cloud server, hosting company, or corporate gateway. In those cases, the visible location describes the exit route, not necessarily the person using it.
