Explain ping6 in Linux - How to ping an IPv6 address in Linux?
Learn: What is ping6 command in Linux, how it can be used to ping an IPv6 address in Linux Operating System? Options of ping6 command.
In the previous post we have discussed about ping command in Linux, which is used to check connectivity (or pint an IPv4 address of node – computer which is connected to the network).
To ping the node (network computer) which has an IPv6 address i.e. to ping or check the connectivity under IPv6 network, ping6 command is used.
Ping6 command uses ICMPv6 ECHO_REQUEST to check network connectivity.
Syntax:
$ping6 <hostname>
Example:
$ping6 fd18:6dc5:3dbc:ce24::1
or
$ping6 host.domain.com
or
$ ping6 ipv6.google.com
or
If network is reachable, then output of ping command:
linux~# ping6 fd18:6dc5:3dbc:ce24::1
