Vista not playing well with IPv6

Microsoft acknowledges some “compatibility issues,” but calls operating system its best ever
By Carolyn Duffy Marsan , Network World , 06/07/2007

Early adopters of Microsoft’s new Vista operating system are reporting problems with its implementation of IPv6, a long-anticipated upgrade to the Internet’s primary protocol.

IPv6 supports a 128-bit addressing scheme, which lets it support an order-of-magnitude more devices that are directly connected to the Internet than its predecessor, IPv4. IPv6 also has autoconfiguration, end-to-end security and other enhancements.

Vista supports IPv6 by default. Vista runs a single-stack, dual-IP-layer architecture, which means it is IPv4- and IPv6-capable out of the box. It supports tunneling of IPv6 traffic over an IPv4 backbone and includes IPSec that works for both IPv4 and IPv6.

Network management software vendors and users are reporting problems with Vista’s IPv6 implementation.

“Vista is showing some serious deficiencies around IPv6 and IPv4 insofar as their compliance or the transparency of their compliance around IP behaviors,” says Loki Jorgenson, chief scientist for Apparent Networks, a provider of network assessment and optimization tools.

“For example, Vista doesn’t expose any of the [Internet Control Message Protocol] errors to applications running on Vista,” Jorgenson says. “The application can’t get access to that message, and subsequently all it sees is that the network connection is not working. This is a big challenge for us around Vista. It’s not clear at all why IPv6 isn’t properly supported in this regard.”

Duane Murphy, president of Managed Information Services in Long Beach, Calif., says he has experienced problems with Vista’s IPv6 implementation on the networks he runs for law firms. Murphy used Network Instruments' Observer 12 application, which supports IPv6, to isolate Vista’s IPv6 problems.

“We are seeing a number of applications that are IP-based that do not like the addressing scheme of IPv6,” Murphy says. “We will send a print job to an IP-based printer, and the print job becomes corrupted. We’re seeing this with Window’s Vista machines. When IPv6 is installed, this happens without fail. As soon as we remove IPv6, all of our printer functions return to normal.”

Murphy says the printing problem has cropped up on 45 Dell Latitudes and Dimensions running Vista Business or Vista Ultimate.
