organizations worldwide. The major effect of the allocation process is that

the Internet IP addresses have been distributed unevenly across the entire

world due to different political boundaries of the owners. This Year 2009

study report analyzes the distribution and the trends of IP address

allocation in 238 countries using historical data. It also compares the

trends with the same IP address report for 2007.

In this first section of the study, we breakdown the average percentages of

IP address allocations in 238 countries using the IP2Location historical data

in 2008. The average percentage is the arithmetic mean of 12-month values

collected on the first day of the month from the IP2Location monthly database.

From the data analysis (please refer to http://www.ip2location.com/

ip2location-internet-ip-address-2009-report.aspx#table1 and http://www.

ip2location.com/ip2location-internet-ip-address-2009-report.aspx#chart1), the

United States tops the allocation list by holding 37.17% of the total IP

addresses worldwide. It is followed by the United Kingdom (11.37%), China (7.

08%), Japan (6.95%), Germany (4.01%), France (3.75%), Korea (2.91%), Canada (

2.66%), the Netherlands (1.91%) and Italy (1.77%). These Top 10 countries in

the list occupied close to 80% of the total allocated IP addresses in the

world in 2008. The other 228 countries are sharing the remaining 20% of the

allocated IP address spaces.

If we compare the data from the year 2007, China has replaced Japan for the

3rd position. The Republic of Korea replaced Canada for the 7th position.

Japan and Canada are in 4th and 8th positions respectively in the year 2008.

In this second section of the study, we plot the month-to-month percentage of

IP address allocations by country using the IP2Location historical data in

2008.

From the chart analysis (see http://www.ip2location.com/ip2location-internet-

ip-address-2009-report.aspx#chart2), the total percentages of the IP address

space allocated to networks in the United Kingdom is decreasing at a slow

pace. The IP address space allocated to networks in China and Japan are

increasing at a fast pace. However, we do not foresee that either country

will be overtaking the United Kingdom for the second position in the year

2009. The network in the United States is maintaining the growth of the IP

address allocation, leading the other 237 countries in the year 2008.
