Create Your Own IP Geolocation Tool in Termux

IP geolocation tools are used to find basic information about an IP address like country, region, city, ISP, and more. In this post, you will create your own simple IP geolocation tool in Termux using the Go programming language. It runs on any Linux terminal and displays IP information in a clean format with a hacker-style banner.

Here’s what you can do with this tool:

• Get IP address details
• Find country and city information
• Identify ISP details
• Learn basic Go programming
• Build your own CLI tool in Termux
• Understand API-based data fetching
