6.4.3 Scenario 3: IPv6 only Network
Having started to implement the Scenario 1 or 2, the final goal is clearly the IPv6 only network. All nodes in
the networks which could be IPv6 enabled communicate via IPv 6 only but they can„t reach IPv4 nodes
which could not be equipped with IPv6 for any reason (old applications not supporting IPv6, old OS, running
on the old hardware etc).
In order to enable also communication between IPv6 only and IPv4 only nodes, so called translation
techniques are being used to convert IPv6 packets into IPv4 ones.
There are many such techniques operating on different layers (application, transport, network) for example
the NAT-PT (Network Address Translator, Protocol Translator) network layer technique directly converting
IPv6 packets into IPv4 independently from the applications.
6.5 KCS IPv6 Support
6.5.1 Basic Strategy
Starting with KCS release 9.0, the migration towards IPv6 protocol has begun with the following final goals:
1. The IPv6 connectivity for KCS applications is supported on Windows Server 2008 and later (link and
server components) and Windows 7 (client applications) only.
However, the same binary code of each IPv6 enabled application will continue to work in IPv4 mode on
each supported older operating system.
2. The KCS Server applications (like TCOSS.EXE, TWS) are able to accept client connections through
IPv4 and IPv6 simultaneously
3. The KCS Client applications are able to connect to their corresponding servers through both IPv4 and
IPv6
The KCS version 9.0 is the first step towards IPv6 support, but it does not include IPv6 support for all
applications/modules.
In the chapter Security Strategy – Network, there is a table with all supported TCP/UDP connections.
P lease refer to the column “IPv6 enabled” for the information, which connectivity has already been enabled
for IPv6 and starting with which KCS version.
6.5.2 KCS Support for Dual-Stack Network
Those KCS applications/modules which have already been IPv6 enabled may use either IPv4 or IPv6 protocol
in the IPv6/IPv4 enabled network:
