A new report says Internet speeds around the world are getting much faster. The report comes from Akamai, a business that provides cloud computing services. But it warns that the sharp increase in the number of devices connected to the World Wide Web could cause problems. The company says this increase might use up all of the remaining space that is currently available on the Internet. The report is called ’’State of the Internet. ’’It examines use of the World Wide Web, Internet and mobile device data speeds, and overall strength of the web.
The report says Internet connectivity continues to grow in every part of the world. The total number of Internet users has reached nearly 3. 2 billion. There are almost two connected devices for every person on the planet. The report predicts that number will increase to three devices per person by 2019.
The report says that worldwide, average connection speeds rose by 10 percent over last year. The international average is now almost five megabits per second. South Korea set a new record with an average speed of 23.6 megabits. Ireland, Hong Kong, Sweden and the Netherlands were among the top five areas with the fastest connections. However, less than five percent of the world’s population has access, or use, of Internet speeds of 25 megabits or higher. The United States still leads the world in the number of unique, or different, Internet addresses.
The report says the growth in the number of connected devices is adding to a new problem: the need for more addresses. Most of the World Wide Web uses Internet Protocol version 4 to govern data traffic. IPv4 has a total of 4.29 billion unique addresses for computers, computer tablets and other electronic devices to connect and direct traffic. But billions of addresses are already being used. Experts use the term ’’Internet of Things’’for all the physical objects that are able to connect to the Internet. Researchers are warning that as the ’’Internet of Things’’grows, IPv4 will not have enough room in the near future. ’’The IPv4 exhaustion issue has been around for many years,’’Mr. Belson told VOA.’’Now it’s really becoming more and more imminent. ’’
