Fatal flaw for IPv6: It's not backwards compatible

The Internet engineering community says its biggest mistake in developing IPv6 - a long-anticipated upgrade to the Internet's main communications protocol - is that it lacks backwards compatibility with the existing Internet Protocol, known as IPv4.

No business case for IPv6, survey finds

Business incentives are completely lacking today for upgrading to IPv6, the next generation Internet protocol, according to a survey of network operators conducted by the Internet Society (ISOC).

Techies bypass feds on DNS security

Forty years ago, when the US government created the packet switching network that became the Internet, one of its goals was to create a robust network where traffic would be dynamically routed around blockages.

Detecting Internet routing 'lies'

Australian Geoff Huston is one of the foremost authorities on Internet routing and scaling issues. We sent Huston, a former Chief Scientist, Telstra Internet, a few questions about the U.S. government's plan to bolster R&D to secure the Internet's core routing protocol, the Border Gateway Protocol (BGP). Here are excerpts of from what Huston had to say:

U.S. plots major upgrade to Internet router security

The U.S. federal government is accelerating its efforts to secure the Internet's routing system, with plans this year for the Department of Homeland Security to quadruple its investment in research aimed at adding digital signatures to router communications.

NTT details IPv6-powered TV service

NTT this week disclosed technical details about what it claims is one of the largest, most successful commercial applications of IPv6, the next-generation Internet network protocol.

Nine Web sites IT pros should master in 2009

Here's a time-saver for IT executives swamped by last-minute budget cuts and end-of-the-year performance reviews: We've written your 2009 goals for you, with our list of nine Web sites you need to study during the next 12 months.

Critics to ICANN: Top-level domain sale dangerous, costly

A controversial proposal to create hundreds of new generic top-level domains is generating harsh criticism as corporations and individuals question the need for additional competition in the domain name marketplace and expense for businesses.

Corporate IT budgets evaporating, report says

US corporate IT spending will plummet 10 to 20 percent in 2009, according to the latest projections from Citi Investment Research, which is reporting a "rapid deterioration" of CIO budgets in recent weeks.

Experts to Feds: Sign the DNS root ASAP

Internet security gurus and leading vendors are urging the US federal government to rapidly deploy security and authentication mechanisms at the top level of the DNS hierarchy, which is known as the root zone.

12 myths about how the Internet works

Thirty years have passed since the Internet Protocol was first described in a series of technical documents written by early experimenters. Since then, countless engineers have created systems and applications that rely on IP as the communications link between people and their computers.

IETF: Should we ignore the Kaminsky bug?

The Internet engineering community is grappling with what to do about a serious flaw in the DNS discovered mid-year, and the ongoing debate brings to mind a famous quotation from Voltaire: "The perfect is the enemy of the good."
