So it is not as much an issue of the network allowing IPv6 as it is the computer running the Blend app allowing IPv6. The BlackBerry component will send over IPv4 but since the source of the traffic was IPv6, on a Windows PC you are required to have enabled IPv6 communication. Where the dependency exists in Blend is that the Windows and Mac clients send IPv6 source traffic to the corresponding BlackBerry desktop components that perform the networking communication themselves. UPDATE – I received a statement from a representative for Blackberry stating that for Blend to work the mobile device (such as the Passport) does not need to have an IPv6 address or connectivity. your network doesn’t have to have actual IPv6 addressing and connectivity to the IPv6 Internet, but your network computer needs to allow IPv6 networking. NOTE – it does not seem to require IPv6 connectivity, i.e. One interesting fact to emerge, though, is that the BlackBerry Blend application requires IPv6 networking in order to function. There was a good bit of media coverage, almost all focusing on the Passport phone itself. Yesterday BlackBerry held a series of events announcing their new “Passport” smartphone as well as an application called “BlackBerry Blend” that lets you use your computer or tablet (including iOS and Android tablets) in conjunction with the Passport phone.
