FckMyIP 作者: Cognitys

FckMyIP is a lightweight browser extension that instantly displays your public IP address -- both IPv4 and IPv6 -- along with geolocation and network details, right from your toolbar.

Click the icon to see at a glance:

• Your IPv4 and IPv6 addresses
• City, region, and country
• Internet Service Provider (ISP)
• Autonomous System Number (ASN)
• Geographic coordinates

Features:

• Clean, dark glassmorphic design with smooth animations
• One-click copy for any IP address
• Direct link to the interactive map on fckmyip.com for full geolocation visualization
• Automatic language detection (English and French)
• Zero permissions required -- the extension only calls the public FckMyIP API, no browsing data is accessed or collected
