Ping IPv6 Address With ping6 Command

One of our client was unable to ping an IPv6 address. Although our Linux based operating system is configured for IPv6 IP address but he was getting error:

ping 2a05:b40:0:102::e681:2ca
ping: unknown host 2a05:b40:0:102::e681:2ca

Regular ping command only works with IPv4 address, So to ping IPv6 host type the commands as below:

ping6 localhost
ping6 IPv6-address
ping6 2a05:b40:0:102::e681:2ca

The best way is to ping global website such as:


Sample output would be like this:
