ping6 command in Linux
The Linux ping6 command is used to test the connectivity between devices using IPv6 addresses. It sends ICMPv6 Echo Request packets to a specified destination and waits for a response. This command is helpful in troubleshooting network connectivity issues specifically related to IPv6 addresses. By analyzing the ping6 output, users can determine if a device is reachable over an IPv6 network and measure the round-trip time for packets to reach their destination. It is an essential tool for network administrators and users working with IPv6 protocols.
