  • IPv6 product testing needed, experts say

    IPv6 products need more conformance testing. That's the conclusion of network industry heavy hitters AT&T, Cisco Systems, Juniper Networks, Lucent Technologies, Microsoft and others, which are developing products that support IPv6, the next generation of the Internet's main communications protocol.

  • IPv6 fears seen unfounded

    Early adopters of IPv6 say deployment of this upgrade to the Internet's main communications protocol is significantly easier than expected and costs less than anticipated.

  • Internet security gets root-level boost

    A year after surviving a massive distributed denial-of-service attack, the Internet's root servers are better fortified against hacker activity, thanks to behind-the-scenes deployment of a routing technique known as Anycast, experts say.

  • Largest-ever IPv6 network launched

    The University of New Hampshire, the U.S. Department of Defense and the North American IPv6 Task Force have joined forces to deploy the largest-ever network based on IPv6, the next-generation of the Internet's main communications protocol.

  • AT&T developing early warning tool

    AT&T Labs is developing a new kind of traffic analysis tool — dubbed Internet Protect — that is designed to provide corporate customers with earlier indications of network attacks.

  • Light at the end of the tunnel

    Despite the downturn, third-quarter investments remained slightly higher than in the first quarter and more than double the amount spent in the third quarter of 1999. Altogether, 870 network hardware, software and services startups received an average of $US15 million each during July, August and September.

  • ICANN expands beyond the dot.com

    The non-profit corporation that oversees the assignment of Internet names and addresses is poised to announce several new top-level domains to complement the popular .com and .net domains. The move is expected to prompt a frenzy of domain-name registrations by corporations seeking to protect their companies and product names from speculators.

  • VC focus on ISPs and Web apps

    The venture capital community remains bullish on the Internet economy, pumping a record $US15 billion into business services, network software and telecommunications startups in the second quarter of this year, according to the latest Price- waterhouseCoopers LLP/Network World Venture Capital Survey.

  • AOL out of standard bake-off

    The Internet Engineering Task Force (IETF) has zeroed in on three technical proposals for creating an instant messaging standard. The three proposals - developed by Cisco Systems, Microsoft, Fujitsu and others - were selected from a field of 10 proposals. AOL's last-minute submission was a general framework for instant messaging interoperability rather than a full-fledged protocol, so it was not chosen for further consideration.

  • New security offerings

    Critical Path has announced a suite of secure messaging services designed to help enterprises protect information assets such as engineering drawings, financial documents and legal agreements transferred over the Internet.

  • New protocol sneaks IPv6 traffic over the Net

    In its battle to get IPv6 widely deployed, the Internet engineering community is pursuing an infiltration strategy reminiscent of the Trojan War. The Internet Engineering Task Force (IETF) is developing a protocol, called 6to4, that hides IPv6 packets inside IPv4 packets, allowing IPv6 traffic to run over an IPv4 backbone. The new protocol is aimed at working around one of the biggest stumbling blocks to the deployment of IPv6: the ISP industry's lack of interest in migrating the core of the Internet to IPv6, an enhanced version of IP. The 6to4 protocol lets network executives migrate to IPv6 whenever they want, regardless of whether their ISPs support IPv6.

  • Web inventor sees baby as 'play space'

    In 1989, Tim Berners-Lee first proposed a global hypertext system dubbed the World Wide Web. Ten years later, the Web is hailed by some as one of the most significant inventions of all time - on a par with Gutenberg's printing press, Bell's telephone and Marconi's radio. Berners-Lee recently published a book called Weaving the Web about how he created this free-flowing communications medium and his vision for its future. Berners-Lee last week spoke with IDG's Carolyn Duffy Marsan about how the Web is changing enterprise network environments
