13. IPv6 communication

It is expected cerca. 2005, IPv6 will be released on a large scale on the Internet, gradually supplanting the existing IPv4 architecture. Since the IP addressing schema will change drastically, it is important for applications to be able to adjust to this changeover period.

It is relatively easy to set up a test IPv6 network right now, and it will not interfere with your existing IPv4 network. However, there are some modifications that need to be made to .NET code in order for it to be used with IPv6 addressing schemes.

This application demonstrates how to send data via TCP/IPv6, set up an IPv6 network as prescribed in  Network programming in .NET (Buy at Amazon UK) (Buy at Amazon US) , run the server and client applications, type in the IPv6 address of the server in the space provided on the client, and any message you wish in the other box. When you press ‘send’ the message will appear on the display-box of the server.

(Source code availabile in the book Network Programming in .NET (Buy at Amazon UK) (Buy at Amazon US) , Chapter 16, Example 2)
