Targeted to a developer with IPv4 experience who wants to migrate to IPv6, this paper introduces IPv6 and shows the important differences between IPv6 and IPv4, including the recommended coding style to run C and Java programs unchanged on IPv4 and IPv6 networks on the Solaris 10 OS.
Migrating to IPv6 on the Solaris OS is extremely easy, because no code changes are needed if TCP/IP sockets are programmed as recommended by Sun, using POSIX compliant getaddrinfo() and getnameinfo() function calls. This style should work unchanged on other POSIX compliant operating systems such as Linux, Microsoft Windows XP Professional, Vista, Server 2003/2008, and so on.
