No - it does not work that way.

No.

IP ranges are assigned to providers - and providers can operate in
multiple countries. And by the way - there is also IPv6.

But you still did not answer what you want to achieve.

If you want to handle different languages, you should better use the
Accept-Language header oft the browser - and even then the visitor
should be able to manually select the language, just in case the browser
does not send an Accept-Language header at all or there is no "known"
language in the list of accepted languages.

Also see: <http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html>

And for example - if you have content in English, French in Italian and
you want to deliver it depending on the users browser settings (yes, the
quality value of each language is ignored, since literally all browsers
send the preferred languages in the order of preference):

<?php
// This is the list of languages we support

$knownlanguages = { 'en', 'fr', 'it' };

// This is the active language in which the content
// is being served - 'en' by default

$activelanguage = 'en';

// Build an array of languages based on the Accept-Language
// header the browser sends

$languages = explode(',', preg_replace('/(;q=\d+.\d+)/i',
'', getenv('HTTP_ACCEPT_LANGUAGE')));

// Now go through the list and check if the browser
// supports any of "our" languages

foreach ($languages as $language) {
if (in_array($language, $knownlanguages)) {
// Language is known, then use this and stop
// checking the remaining entries
$activelanguage = $language;
break;
}
}

// Now $activelanguage contains one of our supported
// languages which is also accepted by the browser
?>

BTW: You can see this in action on my private site
<http://arnowelzel.de>. The code is not identical, but very similar. The
site will redirect to the English or German version depending on what
language the browsers prefers or defaults to German if no "known"
language was given. However it is always possible to change the language
using the "language" links in the header.
