IP Address Lookup — Free Geolocation, ISP & ASN Info

Find geolocation, ISP and ASN for any IP address. Free IP lookup tool with city-level location, timezone and map coordinates. Browser-based privacy.

Features

  • ✓Look up geolocation data for any IPv4 or IPv6 address
  • ✓ISP, organization and ASN information
  • ✓Coordinates, timezone and currency data
  • ✓Connection type detection
  • ✓No API key or registration required
  • ✓Auto-detect your own public IP address on page load with instant lookup
  • ✓Search history stored locally in your browser for quick re-queries
  • ✓ASN routing data showing which networks announce the IP block
  • ✓Copy any field — IP, location, ISP, or ASN — individually to clipboard
  • ✓Threat intelligence feed — checks if an IP is associated with known malicious activity (proxy/VPN/Tor)
  • ✓Currency and timezone display — shows the local currency code, currency symbol, and timezone for the IP's geographic location, useful for e-commerce geo-detection testing
  • ✓Reverse DNS (PTR) resolution — displays the PTR record associated with the IP address, revealing the hostname assigned to that IP for mail server verification and network identification

How to Use

  1. 1Enter an IP address in the input field above
  2. 2Press Enter or click the Search button
  3. 3View detailed location and network information
  4. 4Check the map for visual coordinates
  5. 5Click any data field to copy it to clipboard instantly
  6. 6Use the search history panel to revisit previous lookups
  7. 7Compare your IP details against example IPs (8.8.8.8, 1.1.1.1) by clicking preset buttons
  8. 8Detect VPN/Proxy usage — the tool flags IPs known to belong to VPN services or anonymizers
  9. 9Review the ASN panel to see which organizations announce the IP block and its routing prefix
  10. 10Check coordinates on the interactive map to verify the approximate geographic location
  11. 11Use the threat intelligence section to check if an IP is associated with known malicious activity — useful for evaluating suspicious traffic in server logs before blocking IPs
  12. 12Check the timezone and currency data when testing e-commerce localization — verify that your website's geo-detection matches the IP's actual region for correct pricing and regional settings

Frequently Asked Questions

How accurate is IP geolocation?

∨
IP geolocation accuracy varies. Country-level data is highly accurate (99%+). City-level accuracy is around 60-80% depending on the region. ISP and ASN data is generally very reliable.

Can I look up IPv6 addresses?

∨
Yes, this tool supports both IPv4 and IPv6 address lookups.

Is this tool free to use?

∨
Yes, completely free. No API key, no registration, no rate limiting for normal usage.

What data does this tool show?

∨
It shows country, region, city, coordinates (latitude/longitude), timezone, ISP, organization, ASN, and connection type.

Does this tool store my IP address?

∨
No. The lookup is performed directly from your browser to the API. We do not log or store any IP addresses.

What can IP geolocation tell me?

∨
IP geolocation provides the approximate geographic location of an IP address including country, region, city, and coordinates. It also shows the ISP, organization, and ASN that owns the IP. This data is useful for verifying CDN routing, detecting fraudulent traffic origins, and understanding where your website visitors are connecting from.

What is an ASN and why does it matter?

∨
An Autonomous System Number (ASN) uniquely identifies a network organization that manages IP routing. Large providers like Google (AS15169), Cloudflare (AS13335), and Amazon (AS16509) each have their own ASNs. Knowing the ASN helps identify who operates a given IP block and can reveal whether traffic originates from a known cloud provider, ISP, or hosting company.

How can I tell if an IP is using a VPN or proxy?

∨
The threat intelligence check flags IPs that are known to belong to VPN services, public proxies, Tor exit nodes, or hosting providers commonly used for anonymization. If flagged, the IP likely routes through an intermediary rather than a residential connection. This is useful for fraud detection, geo-restriction verification, and security auditing.

Why does my IP address show a different city than where I am?

∨
IP geolocation databases are not always precise at the city level. Your ISP may route traffic through a central exchange point in a different city, or the geolocation database may have outdated information. For home internet connections through major ISPs, city-level accuracy is typically 60-80%. If precision matters, use GPS-based positioning instead of IP geolocation.

What is the difference between public IP and private IP?

∨
A public IP address is globally routable on the internet and assigned by your ISP. A private IP (like 192.168.x.x, 10.x.x.x, or 172.16.x.x) is used within local networks and is not accessible from the internet. This tool shows your public IP as seen by external servers. Your private IP is assigned by your router and is not visible to this service.

Can I look up historical data for an IP address?

∨
This tool provides current geolocation and network information only. The IP address history — which organization previously owned it, geolocation changes, or reassignment dates — requires a paid IP intelligence service. Your search history is stored locally in your browser for your convenience and is not a historical lookup of the IP itself.

Why do I see different IP information on different websites?

∨
Different IP geolocation services use different databases and update their data at different frequencies. Some services provide real-time data while others may have data that's months old. Additionally, how your ISP routes traffic can cause different 'exit points' to be detected, resulting in different location data across services.
