1- How ping / Traceroute work?

Question

Accepted Answer

Ping and Traceroute are network diagnostic tools used to test connectivity and identify network issues.

Ping sends a small packet of data to a destination IP address and waits for a response. It measures the time it takes for the packet to travel to the destination and back.
Traceroute sends packets with increasing TTL values to the destination, and each router along the path sends back an ICMP message indicating its presence. This helps to identify the path taken by the packets and any network issues along the way.
Ping and Traceroute are commonly used to troubleshoot network connectivity issues, such as high latency or packet loss.
Ping and Traceroute can also be used to test the performance of a network, such as measuring the round-trip time (RTT) or identifying network congestion.
Ping and Traceroute are built-in tools in most operating systems, such as Windows, Linux, and macOS.
