Who's Bogarting the IPs?

File this under “It may be old, but it's new to me and it might be new to you”: over at the blog Modern Life is Rubbish, they've got an article that shows which countries have the most IP addresses per capita and which have the least.

Here's how the article's author did the math:

First of all, I obtained an IP address to country lookup list, which revealed the blocks assigned to each country – from this I was able to calculate the total number of IP addresses allocated to each country. I then divided that total figure by the country's population, giving an indication of the number of IPs available to that country per capita (person).

Here's a world map, color-coded by people per IP addresses. Green is fewest (best); red is highest (worst):

Color-coded map showing people per IP address

Let's look at the ten countries with the most IP addresses per capita. As you might guess, all these couuntries seem like pretty decent places to live. To find out more about each country, click on its flag or its name; you'll be taken to that country's entry in the CIA World Factbook.

1. Vatican City

10.5 IPs per person

2. United States

4.5 IPs per person

3. Canada

2.2 IPs per person
