IP Lookup

About IP Lookup

IP Lookup returns the approximate location and network owner for an IPv4 or IPv6 address: country, region, city, postal code, time zone, coordinates and the organization that announces the address. It is useful when a login, a log entry or a firewall alert names an address and you want to know roughly where it sits and who runs it.

How to use it

1. Type or paste the address into the IP Address box, for example 8.8.8.8 or an IPv6 address.
2. Press Lookup and wait a moment while our server asks a geolocation data provider about the address.
3. Read the IP Information card: country with its two-letter code, region, city, postal code, ISP or organization, time zone and coordinates.
4. Copy any value you need. Rows the provider has no data for are simply left out of the card.

When to use it

• Checking where a suspicious sign-in attempt in your server logs appears to originate.
• Confirming which hosting company or ISP owns an address before you write an abuse report.
• Sanity-checking that a visitor address from analytics matches the country you expect.
• Finding the time zone of a remote server before you schedule a maintenance window.

Questions about IP Lookup

How accurate is the city shown?

Country is usually right, region is often right, and city is a best guess. Geolocation databases are built from registry records and network measurements, so mobile carriers, VPNs and corporate networks can land hundreds of miles from the real user.

Where does the lookup actually run?

On our server, not in your browser. The address you type is sent to us, and we forward it to an external geolocation service and return the answer. Nothing else from your device is included in that request.

What happens if I leave the box empty?

The lookup runs without an address, and because the request is made from our server the answer describes the server's own address rather than yours. To inspect a specific address, including your own, type it in.

Why does it say the address is invalid?

The provider rejects private ranges such as 192.168.x.x or 10.x.x.x and reserved addresses, because they are not routable on the public internet. Enter a public address and try again.

Is there a limit on how often I can look up addresses?

Yes. Lookups are limited to roughly 20 per minute per visitor, and each one gives up after 8 seconds if the data provider does not answer. If you hit the cap, wait a minute and continue.
