Description
You open an unfamiliar site and want to know where it actually lives — a domestic CDN or some overseas box, the same IP as yesterday's phishing page or not — and normally that means a whois lookup, a DNS check, and a trip to an IP-geolocation site. Flagfox collapses all of that into a single flag at the right edge of the address bar: the page loads, the flag tells you which country the server is in, and one click expands the full server detail panel.
It reads the IP of the machine the page is actually served from, not the domain suffix, so a .com hosted in Germany and a .cn routed through a Hong Kong node both show up honestly. If you regularly judge whether a link is trustworthy, or need to confirm which node a CDN steered you to, what it saves is opening a lookup tab every single time.
Flag in the address bar: the flag matches the geographic location of the current page's server IP, and hovering shows the country and the IP without opening anything.
Server detail panel: clicking the flag opens a full page listing hostname, IP, ISP and autonomous system number, country, region, city, latitude and longitude, postal code and local time, with a location map above it.
Built-in tool menu: right-clicking the flag runs whois, DNS records, SSL certificate inspection, security scans, web-archive lookups and speed tests against the current site, each opening the relevant service with the domain already filled in.
Custom actions: the tool list can be edited, and your own lookup services can be added as URL templates that follow the current page's domain or IP.
Look up any address: an input box at the bottom of the panel takes any domain or IP directly, so you do not have to visit a site to check it.
Local lookups: the IP location data ships with the extension and is matched locally, so showing the flag does not fire a request to a third-party server on every page you open.
