  • Artigo

Applies To: Windows 7, Windows 8, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Vista

The version of Telnet Server and Telnet Client included with Windows 7, Windows Server 2008 R2, Windows Vista, and Windows Server 2008 support TCP/IP version 6. It does not change in any way how you use Telnet, except that your host names are allowed to resolve to an IPv6 address, and that you can specify an IPv6 address in your connect command.

Any user account can be used to complete this procedure. Review the details in "Additional considerations" in this topic.

Connecting to a Telnet server by using IPv6

You can perform this procedure using either of the following methods:
