Operating Showcase on an
IPv6 Network
Ipv6 is the next generation Internet Protocol to allow computers and other devices to communicate to one another over a network or the Internet. IPv6 is in its early stage of adoption at this time, so not all networks have implemented this yet. IPv6 is supported on Windows Vista and Windows XP with Service Pack 2 or later.
Showcase uses IPv4 or IPv6 for the following functions:
When Showcase is started and periodically while it is running, Showcase will attempt to verify that it is a legally licensed product. The license validation for a local, node-locked license or a network floating license both use either the IPv4 or IPv6 network interface (referred to as a stack).
The license checkout process can take place over an IPv6 network, but the licensing component requires that the IPv4 network stack be enabled. This is referred to as a "dual-stack" configuration.
For Showcase to validate a license, ensure that both the IPv6 and IPv4 Internet Protocols (TCP/IP) are enabled in the Windows Network Connections properties. Showcase will not launch without the IPv4 stack enabled.
The DirectConnect software (included with Showcase for file translation and tessellation) also requires a dual-stack or an IPv4 configuration to function properly. Ensure that both the IPv6 and IPv4 Internet Protocols (TCP/IP) are enabled in the Windows Network Connections properties.
Hosted sessions can be conducted between two machines on an IPv6 network. If using the hostname, ensure the hostname is valid on both networks. Alternatively, the full IPv6 address (e.g. fe80::211:25ff:fe74:0a0f:c955) can be specified in the "Host Machine Name" when joining a hosted session.
Special note for Windows XP users:
Windows XP users need to set the IPv6 Zone ID when specifying the IPv6 address when joining a session. For example, in the address fe80::211:25ff:fe74:0a0f:c955%4, the Zone ID is "%4" at the end of the IPv6 address. The IPv6 address with the Zone ID can be found with ipconfig /all in a command prompt on the host. Look for "Local Area Connection" and use this address including the Zone ID.
Custom interface (HTML / Flash)
When Showcase is started it initializes a web server to allow Showcase to be controlled by a remote or local web browser (or similar interface). This interface can be controlled on a network using IPv6, but requires some changes to the way that the hostname is specified, for example:
