traceroute6 MacOS command

The MacOS traceroute6 command is a network diagnostic tool used to trace the path that packets take to reach a destination using IPv6. It helps identify network issues such as latency and packet loss by sending packets with varying Time-to-Live (TTL) values and analyzing the responses from intermediary routers. By mapping out the network hops, users can pinpoint where connectivity problems may arise and troubleshoot accordingly. This command is particularly useful for network administrators and individuals looking to optimize their network performance.

traceroute6 Syntax:

Terminal window
traceroute6 [options] destination
