Systems management vendor Kace announced Tuesday it had acquired for an undisclosed sum the intellectual property and principal engineers of Computers In Motion, a small company focused on application virtualization technology.

Internet shines in Beijing

The US federal government is locking down its networks through an ambitious and fast-paced effort to eliminate connections to the Internet that are vulnerable to attack.

We posed a few questions to Russ Housley, chair of the Internet Engineering Task Force, about why the standards body is developing network address translations for IPv6 when IPv6 was supposed to eliminate the need for NATs on the Internet. Here's what Housley had to say.

Until recently, many CIOs didn't know how much electricity their IT equipment used, and they didn't care.

UltraDNS, a managed DNS service provider owned by NeuStar, is offering a load balancing service aimed at e-retailers and other enterprises looking to improve the performance and reliability of their DNS resolutions.

Once a joke, belt phones, pen phones and wristwatch phones are now a reality.

iPhones, broadband and gamers give reason for economic hope.

For a decade, IPv6 has been the classic chicken-and-egg conundrum: There has been little North American demand for IPv6, so US carriers haven't introduced IPv6 services; without commercial IPv6 services available from carriers, US government agencies and businesses can't migrate to the next-generation Internet technology.

The Internet engineering community will be eating its own dog food tonight. For one hour, the 1,250 network experts at the Internet Engineering Task Force meeting will be able to access the Internet only through IPv6. The IETF created IPv6 in the mid-1990s, but this upgrade to the Internet's main communications protocol has not yet been widely deployed -- even by the technology's biggest proponents here. Network World National Correspondent Carolyn Duffy Marsan talked with IETF Chair Russ Housley about the group's IPv6 experiment, why the transition to IPv6 is taking so long, and whether the IETF leadership is starting to panic about IPv4 addresses running out. Here are excerpts from their conversation:

The Internet's leading standards bodies have joined forces to clarify a set of next-generation network transport specifications that critics warned could cause massive interoperability problems for service providers.
