IP Address Lookup
Enter any IP or use yoursWhat Is an IP Address?
An IP address (Internet Protocol address) is a unique numerical label assigned to every device connected to a network. It serves two functions: identifying the host or network interface, and providing the location of that host in the network. IPv4 addresses use four numbers separated by dots (e.g. 192.168.1.1), while IPv6 addresses use eight groups of four hexadecimal digits separated by colons.
This tool uses two free APIs in sequence: ipify.org to detect your public IP address automatically, and ipwho.is to retrieve full geolocation and network details for any IP address. Both APIs require no API key and are free for non-commercial use.
What Data Does an IP Lookup Return?
| Field | Description | Accuracy |
|---|---|---|
| IP Address | The queried IPv4 or IPv6 address | Exact |
| Country | Country where the IP is registered | High (99%+) |
| Region / State | Region or state within the country | Medium to High |
| City | City associated with the IP | Medium (city-level) |
| Latitude / Longitude | Geographic coordinates of the network block | City-level only |
| Timezone | IANA timezone identifier (e.g. Asia/Kolkata) | High |
| ISP | Internet service provider name | High |
| Organization | Registered organization for the IP block | High |
| ASN | Autonomous System Number of the network | Exact |
| Connection Type | Broadband, mobile, corporate, hosting | Medium |
Public IP vs Private IP: What Is the Difference?
A public IP address is assigned by your ISP and is visible on the internet. It is globally unique and allows other computers to reach your network. A private IP address is used within a local network (home router, office LAN) and is not routable on the public internet.
Private IP ranges defined in RFC 1918 are: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to 192.168.255.255. Your router has one public IP facing the internet and assigns private IPs to all devices on your home network using NAT (Network Address Translation).
IPv4 vs IPv6
IPv4 uses 32-bit addresses supporting approximately 4.3 billion unique addresses. The global pool of available IPv4 addresses was exhausted in 2011. IPv6 uses 128-bit addresses supporting approximately 340 undecillion (3.4 x 10^38) unique addresses. Both protocols coexist today and most devices have both an IPv4 and an IPv6 address. ISPs and major content providers support IPv6 alongside IPv4 in a configuration called dual-stack.
What Is an ASN?
An Autonomous System Number (ASN) is a unique identifier assigned to a group of IP networks and routers under the control of a single organization. ASNs are used by the BGP (Border Gateway Protocol) routing protocol to identify different networks on the internet. ISPs, large enterprises, universities, and CDN providers each have one or more ASNs. Knowing the ASN of an IP address tells you which organization controls the network block that address belongs to.
IP Geolocation Accuracy and Limitations
IP geolocation is accurate to the country level in over 99% of cases. At the city level, accuracy varies between 50% and 80% depending on the ISP and region. IP geolocation does not reveal the exact physical address of a device. It shows the registered location of the network infrastructure (usually an ISP exchange or data center) that serves the connection.
VPN users will see the location of the VPN server rather than their real location. Mobile users may see a location that differs from their physical position because mobile carrier IP addresses are often assigned to gateway infrastructure in a central city. Corporate users may see their company's head office location if the company uses centralized internet egress.
