IP Location Finder

	A Chrome extension that identifies the geographic location of IP addresses on a webpage.

Current Version: 1.5.0 | Manifest V3

Features

• Automatic IP Detection: Automatically detects IP addresses (IPv4, IPv6, and IPv4 CIDR notation like 192.168.1.0/24) when you select text on a webpage.
• Geographic Location: Displays the country and city (when available) associated with the selected IP address.
• Flag Icon & Country Code: Displays a flag icon and country code alongside the location information.
• ISP/Organization Info: Shows the ISP or organization name in a tooltip when available from the API response.
• API Failover: Automatically switches to the next API if the current one times out (5s) or fails, ensuring reliable lookups.
• IP Caching: Caches query results to avoid repeated API calls for the same IP address.
• Loading Indicator: Shows a spinning animation on the icon while the IP location is being queried.
• Custom API Support: Allows you to configure a custom API URL with the {ip} placeholder (e.g., https://example.com/api/{ip}/json).
• Multi-language Support: Supports 8 languages: English, 简体中文, 繁體中文, Deutsch, Français, 日本語, 한국어, Русский.
• Clean Display: Displays the location in the format: (FlagIcon CountryCode, City). If city is unavailable, only shows (FlagIcon CountryCode). Error/info messages are shown in color-coded tooltips (red for errors, green for info).
