IP Address Lookup

Enter an IPv4 address, IPv6 address, or domain name to see its approximate geolocation, network owner, and ASN. Lookups are performed by our server through the ipapi.co geolocation service.

How to use this tool

  1. 1

    Type an IPv4 address (e.g. 8.8.8.8), an IPv6 address, or a domain name (e.g. example.com) into the input field.

  2. 2

    Click Lookup to send the query to our server, which fetches the record from the ipapi.co database.

  3. 3

    Read the returned fields: IP, city, region, country, postal code, latitude, longitude, timezone, organization, and ASN.

  4. 4

    Change the value and click Lookup again to check another address; an invalid or rate-limited request shows an error message instead of results.

What is an IP address lookup and how does it work?

An IP address lookup maps an internet address to metadata about where it connects from and who operates it. This tool sends your input to our server, which queries the ipapi.co geolocation API and returns the result; it does not run a WHOIS query or contact the registries directly. Geolocation works by combining Regional Internet Registry allocations (ARIN, RIPE, APNIC, LACNIC, AFRINIC), ISP-published routing data, and inference databases that estimate a location for each block. That is why results are approximate: city-level accuracy is common for fixed broadband, but mobile, satellite, VPN, and CDN addresses often resolve to a carrier hub or datacenter far from the real user, sometimes hundreds of miles off. The tool surfaces ten fields including the resolved IP, city, region, country_name, postal code, latitude/longitude, timezone, the org (the network owner or ISP), and the asn (Autonomous System Number, the identifier for that routing network). Coordinates are decimal degrees pointing at an area centroid, not a street address. You can submit a domain name and ipapi.co will resolve it to an IP before looking it up.

Common use cases

  • Investigating a suspicious login or order by checking whether the IP in your logs resolves to the country and ISP the user claims.

  • Debugging a CDN or DNS issue by confirming which network and region a server IP belongs to.

  • Enriching web analytics or fraud-scoring records with the country, ASN, and organization behind a visitor's address.

  • Verifying that a VPN or proxy is exiting in the expected country before running a geo-restricted test.

  • Looking up the ASN and org of an address that is hammering your firewall logs to identify the responsible hosting provider.

  • Quickly resolving a domain to its hosting location when triaging an abuse report or a downtime alert.

Frequently asked questions

Why is the reported location wrong?▼
IP geolocation is an estimate, not a GPS fix. Mobile carriers, satellite links, corporate VPNs, and CDNs route traffic through hubs that can sit hundreds of miles from the actual user, so the city or even country may not match reality.
Does this tool keep my data private?▼
No, this is not a browser-only tool. The value you enter is sent to our server, which forwards it to the third-party ipapi.co service to perform the lookup. Do not enter anything you would not want passed to that external API.
Can I look up a domain name instead of an IP?▼
Yes. ipapi.co resolves a domain to an IP address before geolocating it, so entering example.com works. Note that a domain may map to a CDN or shared host rather than the origin server's location.
What is the ASN field?▼
ASN stands for Autonomous System Number, a globally unique identifier for the network that announces routes for that IP block. Combined with the org field it tells you which ISP or hosting provider controls the address.
How accurate are the latitude and longitude?▼
They are decimal-degree coordinates for the approximate centre of the IP block's region, not a precise address. Treat them as area-level hints, useful for mapping at city or country scale but never for pinpointing an individual.
Why did I get an error or no result?▼
The lookup can fail if the input is not a valid IP or resolvable domain, if the address is reserved or private (like 192.168.x.x), or if the free ipapi.co tier hits its rate limit. The tool shows the error message returned rather than partial data.
Does this perform a WHOIS lookup?▼
No. It only returns the geolocation and network fields provided by ipapi.co. For registrant contacts, allocation dates, or abuse addresses, use a dedicated WHOIS tool instead.
