What is an IP address?

An IP (Internet Protocol) address is a unique numerical identifier assigned to every device connected to a network. IPv4 addresses use four octets (e.g., 192.168.1.1), while IPv6 addresses use a longer hexadecimal format. Your public IP address is how websites and services identify your connection.

How it works

When you visit a website, your device sends requests from its public IP address, which is assigned by your Internet Service Provider (ISP). This tool queries a geolocation API to look up the location, ISP, and network details associated with your IP address.

How to use this tool

• Open the page to instantly see your public IP address
• View geolocation data including city, region, country, and coordinates
• Check your ISP and network organization details
• Use curl 1tt.dev/ip from a terminal to get your IP in plain text

Common use cases

• Checking your public IP when configuring firewalls or allowlists
• Verifying VPN or proxy connections are active
• Debugging network issues by confirming your visible IP address
• Quick IP lookup from the terminal with curl
