IP What? is a free Chrome add-on designed for monitoring both IPv4 and IPv6 internet connectivity in real-time. It provides users with a visual badge displaying the connectivity status, along with details about local and public IP addresses which can be easily copied. The tool also tracks latency with EMA-smoothed jitter and monitors packet loss, offering a 24-hour historical graph to visualize connection stability.

In addition to its monitoring capabilities, IP What? features an event log that records connection changes and allows users to export their connectivity history to CSV format. It supports dark and light modes based on system preferences and can be configured to ping various targets such as Google and Cloudflare. Notably, IP What? prioritizes user privacy by ensuring no personal data is collected or transmitted, making it suitable for developers and remote workers alike.
