Although we see more than million unique IPv4 addresses, Akamai believes that we see well over one billion Web users. This is because, in some cases, multiple individuals may be represented by a single IPv4 address or a small number of IPv4 addresses , because they access the Web through a firewall or proxy server. Conversely, individual users can have multiple IPv4 addresses associated with them, due to their use of multiple connected devices. In contrast, RIPE was significantly more active, assigning or allocating more than , IPv4 addresses on many days during the quarter, peaking at , IPv4 addresses on 1 December.

Based on data gathered from the Akamai Intelligent Platform , the report provides insight into key global statistics such as Internet penetration, mobile traffic and data consumption, origins of attack traffic, IPv6 adoption and global and regional connection speeds. Marking the end of its first four years of publication, the Fourth Quarter, State of the Internet report includes a section highlighting trending data for several key categories.

Compiled to show changes over time in important State of the Internet report statistics, this data and corresponding analysis provide a snapshot of just how much Internet connectivity has changed since Akamai began publishing the report in This represents 2. Among those countries listed in the top 10 list for the number of unique IP addresses connecting to the Akamai Intelligent Platform during the quarter, the United Kingdom represented the most significant quarter-over-quarter increase at 13 percent, increasing to more than 25 million IP addresses.

Attack Traffic and Top Ports Attacked In the fourth quarter of , China, at 13 percent, generated the most attack traffic observed by Akamai. The United States 10 percent and Indonesia 7. In an examination of attack traffic concentration among the top 10 targeted ports, the report found that the top 10 ports account for 65 percent of the observed attacks.

Port Microsoft-DS ended at the top of the list being targeted by 25 percent of observed attack traffic. Geography appears to play a role in frequency of observed attacks on specific ports. For example, Port 23 Telnet is a favorite target for attacks observed to be originating from South Korea and Turkey, where it accounted for more than five times the number of attacks targeting the next most popular port in both countries.

Seven cities in Europe, including three in Sweden, two in Switzerland and one each in Romania and Latvia were included in the top Within the list of top 10 countries for high broadband adoption, seven are in Europe. The Netherlands, which reached 67 percent high broadband adoption, is ahead of all European nations and number two on the top 10 list.

The United States ranks twelfth at 44 percent. Mobile Connection Speeds and Data Consumption In the fourth quarter of , the average measured connection speed for known mobile providers worldwide ranged from a high of slightly more than 5 Mbps to a low of kbps. Approximately 75 percent of the surveyed providers had average connection speeds above 1 Mbps. Analysis of peak connection speeds for the mobile providers worldwide for which Akamai analyzed data showed that there is still a wide range of speeds being achieved.

For example, a provider in Germany that had an average peak connection speed of Of all the mobile providers analyzed, only three — one in Germany, one in Austria and one in Canada — achieved average peak connection speeds above 20 Mbps, while 32 achieved average peak connection speeds above 10 Mbps and 48 recorded average peak connection speeds greater than 5 Mbps.

Only two mobile providers surveyed did not achieve an average peak connection speed above 2 Mbps. In the fourth quarter of , users at eight of the surveyed mobile providers consumed an average of 1 GB or more per month delivered from the Akamai Intelligent Platform.

Users at 75 of the surveyed providers consumed greater than MB per month of content from Akamai, and users at the remaining 19 providers consumed less than MB per month. Through its relationship with Ericsson, Akamai again included data collected by the equipment provider in the State of the Internet report. According to Ericsson, the volume of mobile data traffic in the fourth quarter of doubled year-over-year and grew 28 percent quarter-over-quarter.

Some of the trends observed include: On a year-over-year basis, average connection speeds in Asia increased 13 percent while Internet users in Oceania have witnessed a percent increase.

Average peak connection speeds in Africa were 55 percent faster than four years ago while users in South America have experienced a percent increase Since , South America has seen a percent increase in high broadband adoption, yet still ranks just above Africa in total high broadband penetration. Narrowband adoption continued to decline globally with all regions reporting similar percentage declines percent.

This report includes data gathered from across the Akamai Intelligent Platform about attack traffic, broadband adoption, mobile connectivity and other relevant topics concerning the Internet and its usage, as well as trends seen in this data over time.
