How does the ICMP protocol work and the tools ping and traceroute?

The article discusses two essential networking tools: ICMP Ping and Traceroute, which are foundational techniques used for diagnosing internet connectivity issues. The author points out that many people, even those in the IT field, lack a complete understanding of how these tools work and what their capabilities are. Ping is a straightforward way to check if another computer or server is reachable on the network, while also measuring the time it takes for a data packet to be sent. On the other hand, Traceroute displays the path data takes from one point to another, indicating all the nodes (routers) along the way. This tool can be incredibly helpful in identifying where delays or connectivity issues may arise. The author encourages learning these tools to better understand what happens to data on the network. In summary, comprehending how Ping and Traceroute function can significantly ease network problem-solving and enhance analytical skills in IT.
