Show-my-ip is a Firefox add-on designed for web development and IT professionals who need quick access to their public IP address. This extension simplifies the process by allowing users to view their IP without navigating to external websites. It is particularly useful for developers who require immediate information about their network settings while working on projects. The add-on is open-source, ensuring transparency and community engagement.

The functionality of Show-my-ip is straightforward; it accesses the user's public IP through a designated API. Importantly, the add-on does not retain any personal information, enhancing user privacy. In the event that the primary API is unavailable, the extension seamlessly switches to a fallback API, ensuring reliability. This subscription-based tool is a practical addition to any developer's toolkit.
