IP lookup data comes from ipwho.is, a free public API. Your searches are not stored or logged by us.

What is the IP Address Lookup?

An IP address lookup is a service that maps a public IP address (like 8.8.8.8) to real-world information: the city and country where the device is registered, the ISP operating that address, the timezone, and sometimes the approximate latitude and longitude. It works by querying public IP geolocation databases that track IP ownership and geographic allocation.

How it works

The tool accepts an IPv4 address (192.168.1.1 format) or IPv6 address (longer hexadecimal format) and queries geolocation databases maintained by regional internet registries. These databases map IP ranges to geographical regions, ISPs, and network operators. The lookup returns latitude/longitude coordinates (usually accurate to within a city block or broader area), the registered country and city, the ISP name, the autonomous system number (ASN), and reverse DNS hostname if available.

How to use the IP Address Lookup

  1. Enter an IP address (IPv4 like 192.0.2.1 or IPv6 like 2001:4860:4860::8888) into the lookup field
  2. Click 'Lookup' or press Enter to query the geolocation database
  3. Review the returned data: country, city, latitude/longitude, ISP name, and timezone
  4. Check the ISP and autonomous system (AS) details to understand who operates that address
  5. Use the timezone to understand local time at that location
  6. Cross-reference with your logs if troubleshooting access or traffic

Benefits

  • Instantly identify the geographic origin of traffic, helpful for fraud detection or security audits
  • Troubleshoot connectivity issues by confirming which ISP and region a server is in
  • Verify website visitor locations for compliance, analytics, or user experience decisions
  • Understand timezone differences when coordinating with remote servers or services
  • No software installation needed—runs entirely in your browser
  • Free and unlimited lookups with no login required

Tips & common mistakes

Common mistakes

  • Assuming IP geolocation is precise to a street address—it typically narrows down to a city or region, sometimes inaccurately by several miles
  • Forgetting that VPNs, proxies, and CDNs mask the true user location, so the IP may belong to a data center rather than the actual device
  • Confusing ISP location with user location—the IP's registered data center may be far from where the person actually is

Tips

  • Use a free IP lookup when you spot suspicious login activity or traffic spikes to confirm the source region
  • Remember that IPv6 addresses are increasingly common; make sure your tool accepts both IPv4 and IPv6 formats
  • If you're troubleshooting a blocked IP, check the ISP and ASN to understand if it's a data center, residential, or mobile network

Frequently asked questions

Is IP geolocation accurate to the exact address?

No. IP geolocation typically pinpoints a city or region, accurate within 5–50 km depending on the database and IP type. Residential IPs are often less precise than data centers. VPNs and proxies make accuracy worse.

Can I look up a private IP address like 192.168.1.1?

No. Private IP addresses (192.168.x.x, 10.x.x.x, 172.16–31.x.x) are not routable on the internet and have no geolocation data. Lookup tools only work with public IP addresses.

What's the difference between IPv4 and IPv6?

IPv4 uses 32-bit addresses (4 dotted numbers like 8.8.8.8), while IPv6 uses 128-bit addresses (hex format like 2001:4860:4860::8888). IPv6 was created to handle the billions of devices now online. Both can be looked up the same way.

Why does my IP show a city I'm not in?

Your ISP or VPN provider may have servers or registered address blocks in a different city than you. Also, geolocation databases update slowly and sometimes use the ISP's headquarters rather than the actual server location.

Is using an IP lookup tool legal and safe?

Yes. Public IP lookups are legal and safe—you're only querying publicly available information. There's no hacking involved, no private data is exposed, and anyone's public IP can be discovered by simply visiting your website.

Can I look up multiple IPs at once?

Most basic tools do single lookups, but some services offer bulk IP lookup via CSV upload or API. For a few addresses, running them one at a time is quick enough.
