Internet Protocol Version 6 (IPv6)

It is important to ensure that new Winsock applications as well as existing applications are fully compatible with IPv6.

A growing percentage of new websites and services are available using IPv6 addresses. Many Internet users in emerging markets are dependent on IPv6 for Internet access.

Microsoft has a long commitment of supporting IPv6. Full IPv6 support is provided on Windows XP with Service Pack 1 (SP1) and later.
