Microsoft Leverages IPv6 With Vista

For Microsoft, it meant finding the best way to enable businesses to deliver emerging applications, such as messaging, Internet-protocol television ((IPTV), collaboration, secure-remote access to in-home networks, voice over Internet protocol (VoIP) and multiplayer video games. And have customers enjoy the experience without getting frustrated.

When Vista is released it will offer new search, security and digital entertainment features. A new version of Windows Media Center will ship in the Windows Vista timeframe that adds support for CableCard technology, enabling viewing and recording high-definition programming without a set-top box.

Internet Explorer also promises improved security protection, better graphics and new user interface with collaborative features.

NAT also presented hurdles for Vista's connectivity features that were resolved with IPv6. The connectivity features in Vista must have a reachable IP address from remote locations, O'Donovan said. "If the connection is initiated from outside the home the NAT locks up and you don't have a way of addressing the PC," she said. "Reaching the devices isn't possible unless you custom configure an application."
