How are you going to find the users nation? IP address is not reliable.
Let's try a different question. What are you trying to accomplish?

almost impossible to RELIABLY detect nation by means of IP address - and
what about French speakers on holiday in Zululand, anyway?
So mostly let user select a country and set a cookie, or redirect to a
country specific part of the site.

It is not possible to do this *reliably*.
You can /infer/ location (and, thus, country) from the client's IP address
($_SERVER["REMOTE_ADDR"]) and various third-party tools, but this location
is often practically inaccurate, and is theoretically not usable at all.
As for techniques and third-party tools, Let Me Google That For You
http://lmgtfy.com/?q=IP+geolocation
Please note that it *is possible* to have, for instance, an IP address
nominally from a European source, originating from North America, or vice
versa. And, let's not forget tools like Tor, that provide "country-local"
IP addresses for remote systems, by way of an encrypted piping mechanism.

Actually, cross-posting is the PREFERRED way of posting to multiple
(appropriate) newsgroups. Multi-posting is frowned upon, though.
In this case, both newsgroups he posted to were appropriate for the
subject (at least based on current information).

However, asking a question in multiple newsgroups might easily lead to
separate discussions even when the OP was *cross*-posted, what is not
preferable, IMHO. And as I do not prefer to (cross-)post to newsgroups
which I am not subscribed to, because I might miss an important reply,
my reply already has split the discussion.

Isn't *anything* that is on topic here also on topic in alt.php?

Yes, because YOU changed the posting newsgroup. Don't change list of
newsgroups being cross-posted to.
Whether YOU prefer it or not is immaterial. It is the accepted practice
on Usenet. A good description can be found at
http://en.wikipedia.org/wiki/Crossposting.

Possibly. But that's life. It doesn't mean messages can't be
cross-posted to both newsgroups. And whether you read both newsgroups
or not is also immaterial. Some people may, for instance, read alt.php
but not comp.lang.php.

If the Followup-To header field is specified properly, so as to avoid the
condition you are describing, there is no intrinsic problem with crossposts.
Mr. Stuckle is correct there.

In theory, yes. But there is no alt.php except on Google Groups and similar
archives, and peculiarly maintained news servers.
The problem with *this* crosspost is that, *and* that alt.ALL – by contrast
to comp.ALL – does not belong to the Big 8. Where comp.ALL is order,
alt.ALL is anarchy; it is therefore a bad idea to crosspost to alt.ALL /and/
comp.ALL. In general, crossposting across hierarchy borders is a bad idea
for several reasons.

My apologies -- I wasn't aware that changing the list of newsgroups

Until now, I have used the follow up header only to point the discussion
to an appropriate newsgroup. Apparently, there are other good uses.
Thanks for pointing that out.

It seems the domain is not accessible (for me); it responds with 403:

It's not - if you're removing newsgroups which are no longer appropriate
(possibly because of the changing nature of the discussion).

Well, I am in (and from, by the way) Germany -- however, geolocation
detection might not properly work.
Anyway, the wayback machine got the same response on Dezember 8, 2013[1].

This utility reporsts the country based on user's location.
But why not let the user select the proper page wotj a dropdown list?

I am in Switzerland, and it WFM in any browser on both GNU/Linux and
Windows, with clean browser cache, respectively. There is no login
required; it is a public FAQ (not by me).
I do not think any geolocation filter is used, because it was written for
the German-*speaking* Usenet which has participants worldwide. I suspect it
might be a User-Agent filter, which would also explain why the Wayback
machine could not access that resource.

That's funny, you always say you can't determine a users location by
their IP.
So which is it?

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?

Once you have learned to write an coherent question, one might be able to
help you.
Please also learn to quote. The attribution lines are relevant as a posting

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>
> 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
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.

No.
And your organisation might cover a continent or be worldwide. You
would use the same IP range for the whole network.

You can't find the user's nation automatically in any even halfway
reliable way.
But again - what are you trying to accomplish? Not how should you do
it. What's your goal here?

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

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.

Select random from worlds ten most internet connected countries is
probably almost as accurate as IP based country determination.
(may contain some exaggeration)

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
