In computing, traceroute and tracert are computer network diagnostic commands for displaying possible routes (paths) and measuring transit delays of packets across an Internet Protocol (IP) network.

What is tracert command for?
The tracert command (spelled traceroute in Unix/Linux implementations) is one of the key diagnostic tools for TCP/IP. It displays a list of all the routers that a packet must go through to get from the computer where tracert is run to any other computer on the Internet.

What is traceroute and how does it work?
A traceroute works by sending Internet Control Message Protocol (ICMP) packets, and every router involved in transferring the data gets these packets. The ICMP packets provide information about whether the routers used in the transmission are able to effectively transfer the data.
Why would traceroute fail?
There are several possible reasons a traceroute fails to reach the target server: The traceroute packets are blocked or rejected by a router in the path. Usually, the router immediately after the last visible hop is the one causing the blockage. Check the routing table and the status of this device.
What does it mean when tracert times out?
Request timed out
A “Request timed out” message at the beginning of a traceroute is very common and can be ignored. This is typically a device that doesn’t respond to ICMP or traceroute requests, as shown in Hop 2.

What is the purpose of ICMP messages?

How to Make Best Use of Traceroute
- Look for The Obvious. Sometimes a traceroute will immediately reveal where a problem lies in the network, like when it times out on a specific hop and does not recover.

- Find Patterns Over the Entire Report.
- Utilize IP Address and DNS Information.
What does traceroute do in Linux?
traceroute command in Linux prints the route that a packet takes to reach the host. This command is useful when you want to know about the route and about all the hops that a packet takes.
Does traceroute use Ping?
Think of traceroute as a string of ping commands. At each step along the path, traceroute identifies the hop’s IP as well as the latency to that hop.On a Windows system, traceroute uses ICMP. As with ping , traceroute can be blocked by not responding to the protocol/port being used.
