Traceroute
Save
Traceroute is a command-line utility that allows you to trace the path that data takes from your computer to a remote host. It is a valuable tool for troubleshooting network connectivity issues, as it can help you identify where along the path the problem is occurring. Traceroute works by sending a series of packets to the remote host, each packet with a different time-to-live (TTL) value. The TTL value specifies how many hops a packet can take before it is discarded. As each packet is sent, the TTL value is decremented by 1. When the TTL value reaches 0, the packet is discarded and an ICMP Time Exceeded message is sent back to the source host. Traceroute uses the ICMP Time Exceeded messages to determine the path that the packets take from the source to the destination.
