WorldIP for Firefox shows the real location of web server, IP, Datacenter, Ping, Traceroute, RDNS, and AS. It often shows different countries from similar add-ons, because it is based on data from core routers worldwide, and not on whois data. It can display your own IP address and provider. WorldIP extension is one of WIPmania's products based on WorldIP geolocation database. The database is more correct than Whois records and Whois-based databases that show geographic locations of network owners, and not the geographic location of networks themselves.
