This is the VOA Special English Technology Report, from voaspecialenglish.com | http June eighth was World IPv6 Day — the first major deployment of Internet Protocol version 6. Hundreds of Internet service providers and Web companies tested IPv6 on their websites. This new numbering system for Internet addresses has been available for years. But very few companies have switched to it. Yet the old system could run out of addresses this year because of all the growth in online devices. Computer science professor Doug Szajda at the University of Richmond in Virginia explains: “It’s sort of like the post office of the Internet. It tells you how to get information from one computer to another. Currently, and since around nineteen eighty, the addressing system has been IP version 4. But the problem with that is that we’ve run out of addresses. So it’s almost as if, when a new house is built, you can’t give it an address because you don’t have any more.” IPv4 was designed to handle just over four billion IP addresses. Doug Szajda says that seemed like more than enough. “At the time that IP version 4 was designed, the designers were anticipating perhaps thousands of users of the Internet someday, and certainly thinking that four billion addresses was many more than we would ever need.” Yet now, not just computers but smartphones, cars, televisions, game systems and plenty of other devices all connect to the Internet. Each uses a different IP address. The basic standards for IPv6 …

They came to present their ideas for using technology to solve world problems. Microsoft education director Suzi Levine says the nine-year-old program began mainly as a competition to create technology. She says, “When we realized that students really actually want to have a purpose for what they’re creating, we introduced the idea of inspiring them with the UN Millennium Development Goals and suggesting that they use those for their muse.” New sources for ideas this year included intergovernmental and nongovernmental organizations and nonprofits. They can submit some of the technical challenges that they would like students to consider for their solutions.Microsoft says over three hundred fifty thousand high school and college students registered for this year’s competition. Judges chose more than four hundred of them to attend the finals. Ms. Levine says several teams were inspired by current events, including floods last year in Thailand. A team from Chulalongkorn University in Thailand “created a Windows Phone 7 application that allows you to broadcast your location to your social network of friends so that you can be more easily rescued.” There were also ideas from Egypt inspired by the revolution that overthrew president Hosni Mubarak in February. Ms. Levine says one …
