| Traceroute and Traceroute6 are both network diagnostic tools, but they are designed for different network protocols. Here's the key difference between them: Traceroute is for IPv4, while Traceroute6 is for IPv6. Depending on the network infrastructure you are dealing with, you would choose the appropriate tool to trace the route of packets. Many modern systems support both IPv4 and IPv6, so you might use either tool based on the type of address you're working with. Sometimes, you may need to check if remote server is reachable by traceroute like below: traceroute foo.com
Above shows the result like below which is based on IPv4 % traceroute yahoo.com
