Internet policymakers are considering sweeping changes to the way they distribute IP addresses that could allow network operators to make money by transferring unused blocks of IPv4 address space to others in need. One result could be lessened incentive to move to IPv6 any time soon.
Spoofers, spammers and phishers, beware. There's a new gun in town, and some of the Internet's most powerful companies -- including Yahoo, Google, PayPal and AOL -- are brandishing it in the ongoing battle against e-mail fraud.
Who's afraid of IPv4 address depletion? Not IT professionals, according to a new survey due this week by BT INS, a Californian consulting firm.
Members of the Internet engineering community have raised several new security concerns about Teredo, a mechanism for sending IPv6 traffic over IPv4 networks that comes turned on by default in Microsoft's Vista software.
The Internet has 1.3 billion users, but that's not enough for Lynn St. Amour. As CEO of the Internet Society, she is expanding the nonprofit group, which promotes development of the Internet globally. St. Amour doubled the group's staff in 2007 and beefed up its outreach activities in Africa, South America and Asia in her bid to add another billion Internet users worldwide. National Correspondent Carolyn Duffy Marsan sat down with St. Amour this week at a meeting of the Internet Engineering Task Force, an ISOC-funded standards group. Here are excerpts from their conversation:
Verizon Business and Level 3 Communications will share a multibillion contract to provide local telecommunications services to US federal agencies in the Washington, D.C. area.
Some of the world's top network engineers are engaged in a research effort that could lead to the most radical redesign of the Internet's underlying routing architecture since it was developed in the 1980s.
For a decade, IPv6 proponents have pushed this upgrade to the Internet's main communications protocol because of its three primary benefits: a gargantuan address space, end-to-end security, and easier network administration through automatic device configuration.
If you think migrating to IPv6 is as simple as upgrading to Microsoft Windows Vista, think again.
Network engineers completed their first-ever test of common enterprise applications over the world's largest IPv6 network this summer -- and the results announced today were mixed.
Increasingly popular social-networking sites such as MySpace, YouTube and Facebook are accounting for such huge volumes of DNS queries and bandwidth consumption that carriers, universities and corporations are scrambling to keep pace.
The IPv6 movement got a boost in May when the American Registry for Internet Numbers announced it would actively encourage migration to IPv6. ARIN distributes blocks of IP addresses to service providers and enterprises based in North America. Other stories on this topic
