Can I identify country from IP address?

How many IP addresses per country?

It's common to hear people say "I have to buy a new IP address for the next country".

That's probably a mistake. What they should do is buy more than one IP address.

It's common to hear people say "I have to buy a new IP address for the next country". I know I have to get more than 1 IP for Germany, US and UK, but what about the other countries like Argentina, Italy or Brazil? Do they have to buy more than 1 IP per country? Yes. Every country has a different allocation table.

I'm sorry, I don't speak of IP addresses anymore, I speak of numbers. We are talking about 10 of us here, and we have several computers. Is it necessary to have 10 computers? or is it possible to use only 2? If it's not possible, how many number does each country need?

Each country needs the minimum amount to keep the internet up, plus a number which can be increased if needed. You should buy them so that you will never need to buy any IP's from the ISP. You will be using one of your already purchased IP's for the whole time you own it.

Also, in other words, do certain ISPs have different address allocations by country, or has the use of IP addresses been standardized on a country-by-country basis, and if the former is true, why is it not used by most people? Thanks. (edited 26.06.13) ~~~

Also, in a broader context, what is the average percentage of Internet use for a given country? The majority of countries are developing nations, thus the percentage of usage should be low. I'm talking strictly about average, not for specific purposes and areas.

(edited 26.13) ~~~ I've researched many web sites concerning Internet Protocol address allocation, but I could only find a simple description as "It depends on a lot of technical factors." Thus, I am looking for some basic, plain to see facts about this topic (or simply explanations like the one about telephone numbers).

Answer: An "ip assignment" may vary by country. It can also depend on the ISP or private address holder that is using the IPv4 network, etc. There is still, in my opinion, a wide range of variability in the "countrywide" assignment of IP blocks. In addition, even the same private entity may own some block within a country and some without. There is no universal standard as to the assignment of IP blocks by regions or countries.

The "assignment" of ip addresses from the pool of ip addresses ranges are usually set up and controlled by a particular service provider. Thus, there are usually different ways of obtaining IP blocks. In the case of your question, ip addresses obtained by companies such as Google would generally obtain theirs through a block of ip addresses offered by Google which is typically assigned for all the world. Most of the internet's population would fall under this class of ip addresses.

There's actually quite a wide spectrum of the IP address allocation models, so please be more specific in what it is you are concerned with. Many of those companies I mentioned are involved in providing services for different countries/regions, so that may explain the difference.
