Why WorldIP is different to other add-ons and services in showing country
WorldIP plugin often shows different results from similar plugins and add-ons, because it based on data from core routers worldwide, and not just on whois data. So, it displays real geographic location of an IP address, you can easy check it, just trace this IP address.

Most often users are interested in results on Google's servers
Google has data centers located all over the world and shows a website to the user from the nearest server. WIPmania shows the real countries for Google where these data centers are.
And, according to whois, United States of America (US) is always displayed for Google, because their head office is in Mountain View, California, US

There are some CDN-Hosters (among them, the largest one is Akamai). They have also servers worldwide and also show the website to the user from the nearest server. WorldIP shows the real country of the server as well, and not the US, AP or EU, like others databases and add-ons.

For example: "www.seagate.com" is displayed for Japan's users from the server in Japan (with IP address 59.151.168.134). For users from Canada it is shown from Chicago (96.7.116.134).

Opera mini uses the proxy servers for Internet access, some of them are located in Norway. WIPmania displays an external IP address and country of these proxies (Norway ), you'll see by accessing the Internet on your mobile phone, and not the country where you are from.

If the country is not displayed (Unknown, Asia, Europe ), most likely it happens because:
a) the IP address is not accessible from the Internet, because of the internal network (corporate or of your internet provider), or
b) the network is new, so that it is still unknown for all core routers on the planet. (BGP route announcements about the new network can be spread over several hours around the planet).
с) For the routing to this IP address "anycast" technology is used. Which means, the same IP address is located in different countries. As in the case of the ordinary CDN, the website is shown to the user from the nearest server, with one difference, that all these servers have the same IP address.

An example: CDN-hoster Edgecast.com (their servers are in America, Europe, Asia).
