IP Lookup / My IP

About this tool

IP Lookup retrieves geolocation and network metadata for any IPv4 address - or detects your own public IP automatically. The metadata includes country, region, city, ISP name, ASN (Autonomous System Number), and organization. This is useful for network troubleshooting, incident response, firewall allowlist verification, and quickly identifying who owns a given address block.

Real example

Input: 8.8.8.8 (Google's public DNS resolver)

Expected result fields:
ip: 8.8.8.8
org: AS15169 Google LLC
city: Mountain View, region: California
country: US, postal: 94043
timezone: America/Los_Angeles

The ASN (AS15169) is the key identifier - it tells you which organization controls this IP block at a routing level, regardless of the imprecise geolocation city data.

Common use cases

• Firewall allowlist verification: If your application only accepts traffic from specific IPs, use "Find My IP" to confirm your current egress address matches the allowlisted entry before debugging a connection failure.
• Incident response and abuse investigation: When reviewing logs during a security incident, look up the source IPs to identify the hosting provider or ISP. Combine with WHOIS Lookup to find abuse contact information.
• CDN and proxy detection: Cloud providers (AWS, Cloudflare, GCP) have well-known ASNs. If traffic from an unexpected ASN appears in your logs, this lookup quickly identifies the source organization.
• Geolocation debugging: If your application serves region-specific content and a user reports seeing the wrong region, look up their IP to see what metadata your geolocation library would return for their address.

How it works

"Find My IP" calls the ipify.org API (https://api.ipify.orgformat=json) to detect the public IP of the browser's current network connection. The IP lookup calls ipapi.co to fetch metadata associated with any IPv4 address. Both calls are made directly from your browser - the results are displayed in the output panel and are not stored by this site.

Common mistakes

• Expecting precise city-level geolocation: IP geolocation is a best-effort estimate based on registration data and network routing. The city shown may be the ISP's headquarters or a major routing hub, not the actual device location. Accuracy varies significantly by provider and region.
• Confusing egress IP with device IP: When behind a NAT router or corporate proxy, your device's private IP (192.168.x.x) is not your public IP. "Find My IP" returns your public egress address - the IP seen by external servers.
• Treating VPN results as real location: If you are on a VPN, the lookup returns the VPN exit node's location and ASN, not your actual location or ISP.

FAQ

What is an ASN
An Autonomous System Number (ASN) identifies a network operated by a single organization under a unified routing policy. Major cloud providers, ISPs, and CDNs each have one or more ASNs. AS15169 is Google, AS16509 is Amazon AWS, AS13335 is Cloudflare.

Why does geolocation show the wrong city
IP geolocation databases map IPs to locations based on ARIN/RIPE registration data and routing analysis. The result is often the ISP's data center city, not the actual user location. For precise location, GPS or user-provided data is needed.

Does this tool store my IP
No. The lookup is performed by your browser and the result is displayed locally. This site does not log or store IP addresses.

Can I look up IPv6 addresses
The tool currently supports IPv4 only. For IPv6 metadata, use a dedicated WHOIS or RDAP lookup via WHOIS Lookup.
