but isn't stable the ip of the nations?
example
  50.xxx.xxx.xxx  to 100.xxx.xxx.xxx     all ip nation  A
 101.xxx.xxx.xxx  to 150.xxx.xxx.xxx     all ip nation  B
 151.xxx.xxx.xxx  to 200.xxx.xxx.xxx     all ip nation  C

ok the ip inner nations ip can't be accurate and can to change, but between
nation is table (every range is assigned at only one nation)?

There are IP-numbers which is registred for say Sweden and users in 
Denmark will be using those IP-numbers, which makes it look like the 
Dane comes from Sweden and you your case you would server them something 
in Swedish which ain't Danish. This applies for Hi3G users, sure you 
could adjust and tell that those IP-numbers should get things in Danish, 
but then the Swedish users will get it in Danish too.

There are quite many such ranges and some companies lets other companies 
to use part of their range to thir party which may not come from the 
same country.

GeoIP does have quite okey lists, but only if you are paying for it, the 
free lists has loads of known issues.


Sadly you didn't answer Jerrys question, why do you want to do this, 
detect the users country?

No.  First of all, nation and country are different subjects.  A country can 
have, and I daresay by now most countries do have, inhabitants from several 
nations.  There is also the increasingly likely possibility for a person to 
have multiple nationalities.

Second, IP address ranges are allocated to *Regional* Internet Registries 
(RIRs), which then allocate them for Local Internet Registries (LIRs).  LIRs 
include Internet service providers, enterprises, or academic institutions:

<https://en.wikipedia.org/wiki/IPv4#Allocation>
<https://en.wikipedia.org/wiki/IPv6_address#IPv6_address_space>

>  151.xxx.xxx.xxx  to 200.xxx.xxx.xxx     all ip nation  C

This cannot be correct because several address ranges within those ranges 
are reserved for special use already:

No.  Why do you want to determine the nation/country?

Halt Maul, du Esel.

Oh, *do* shut up, PointedHead, you jackass. *Obviously* English is not his first language. 
And he likely figured that -- given the prevalence of English speakers in the computer 
language newsgroups -- that he stood a better chance of getting a good answer to a 
question posed in halting, broken English than one posed in perfect Albanian or whatever 
his native language is.

Maybe a little sparse, but he is quoting properly.

added alt.php back in to the list, since it is appropriate to this 
discussion.

No.

And your organisation might cover a continent or be worldwide. You
would use the same IP range for the whole network.

No.  IP addresses do not know national boundaries.

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.

every range is assigned to many more than one nation.

Blocks down to 256 IP addresses are allocated more or less randomly 
among countries.

And that's before you consider mobile devices...proxies...and NAT

That's funny, you always say you can't determine a users location by
their IP.

So which is it?

No, it does not. It reports the country based on the *presumed* location of the user's 
*presumed* IP address -- which is *not* a reliable indicator of the actual location of the user.

Select random from worlds ten most internet connected countries is 
probably almost as accurate as IP based country determination.

(may contain some exaggeration)
