What Is an IP Address Lookup Tool?
An IP address lookup tool reveals geographic and network information associated with an IP address. It can identify the approximate location, ISP (Internet Service Provider), organization, and other metadata linked to any public IPv4 or IPv6 address.
How to Use This IP Lookup Tool
- Your public IP address is automatically detected and displayed when the page loads.
- Additional details such as city, region, country, ISP, and timezone are shown when available.
- Click “Copy IP” to copy the address, or “Refresh” to re-fetch the information.
Key Concepts
Every device connected to the internet has an IP address. IPv4 addresses use 32 bits (e.g., 192.168.1.1) while IPv6 uses 128 bits (e.g., 2001:0db8::1). Geolocation databases map IP ranges to physical locations based on ISP registration data. The accuracy is typically at the city level for most consumer connections.
Frequently Asked Questions
How accurate is IP geolocation?
City-level accuracy is typically 50-80% for consumer IPs. Country-level accuracy exceeds 99%. VPNs and proxies will show the server location instead of the user’s actual location.
What is the difference between IPv4 and IPv6?
IPv4 provides about 4.3 billion addresses using 32-bit format. IPv6 expands to 128 bits, providing 340 undecillion addresses to accommodate the growing number of internet-connected devices.
Can I look up private IP addresses?
Private IPs (10.x.x.x, 172.16-31.x.x, 192.168.x.x) are not routable on the internet and cannot be geolocated. They are used within local networks only.
