IPv6 Telnet 
Telnet protocol belongs to application layer protocols of the TCP/IP protocol suite, and is used to 
provide remote login and virtual terminals. The device can be used either as a Telnet client or a Telnet 
server. 
As the following figure shows, the Host is running Telnet client application of IPv6 to set up an IPv6 
Telnet connection with Device A, which serves as the Telnet server. If Device A again connects to 
Device B through Telnet, the Device A is the Telnet client and Device B is the Telnet server.
