IP Address Lookup
Look up any IP address for geolocation, ISP, AS number, timezone and VPN/proxy detection. Auto-detects your public IP on load. Google Maps link. Free, instant.
How to Use the IP Address Lookup Tool
Enter any IPv4 or IPv6 address to look up its geolocation, ISP, organisation, AS number and timezone. Furthermore, leave the field blank to detect your own public IP address. Additionally, results include a direct Google Maps link for the approximate location.
- Enter an IP or leave blankEnter any public IP (e.g. 8.8.8.8 for Google DNS). Furthermore, blank detects your own public IP. Additionally, private IPs (192.168.x.x) cannot be looked up.
- Click Look UpQueries ipwho.is for geolocation data. Furthermore, free and no API key needed. Additionally, results return instantly.
- Read location and ISP dataCity, region, country, ISP and organisation shown. Furthermore, AS number identifies the network operator. Additionally, timezone is useful for scheduling.
- View on Google MapsClick the map link for approximate location. Furthermore, IP geolocation is city-level, not street-level. Additionally, VPN users show VPN server location.
- Copy the resultFull JSON result for documentation or analysis. Furthermore, data includes all fields from ip-api. Additionally, useful for network troubleshooting and security analysis.
What Is an IP Address?
An IP address is a unique numerical label for every internet-connected device. Furthermore, IPv4 uses four octets (e.g. 192.168.1.1) while IPv6 uses hexadecimal groups. Additionally, public IPs are internet-routable while private IPs exist only on local networks.
IP Geolocation Accuracy
IP geolocation is typically accurate to city level for residential connections. Furthermore, commercial and VPN IPs locate to data centre locations. Additionally, mobile carrier IPs locate to cell tower aggregation points rather than exact user positions.
IP Lookup Use Cases
| Use case | How IP lookup helps |
|---|---|
| Security analysis | Identify origin of suspicious traffic or attacks |
| Content delivery | Serve region-appropriate content via CDN routing |
| Fraud detection | Verify transaction location matches billing address |
| SEO and analytics | Understand traffic geographic distribution |
| Network troubleshooting | Identify ISP routing issues or slow paths |
VPN, Proxy and IP Masking
VPN users show the IP of the VPN server, not their real location. Furthermore, proxy servers similarly mask the true IP address. Additionally, Tor network traffic exits through random relay nodes showing the exit node location which changes frequently.
IPv4 vs IPv6
IPv4 uses 32-bit addresses providing 4.3 billion possible addresses and is running out of available space. Furthermore, IPv6 uses 128-bit addresses providing virtually unlimited address space. Additionally, most modern websites and ISPs support both protocols in parallel.
Private vs Public IP Addresses
Private IP ranges are used within local networks and are not internet-routable. Furthermore, your router uses NAT (Network Address Translation) to map private IPs to the public IP from your ISP. Additionally, looking up a private IP address returns no geolocation data since these exist only within internal networks.
AS Numbers and Network Identification
An AS (Autonomous System) number identifies the network operator — ISPs and large organisations each have unique AS numbers. Furthermore, AS data is managed by regional internet registries (ARIN for Americas, RIPE for Europe, APNIC for Asia-Pacific). Additionally, AS information reveals the upstream network provider and peering relationships.
