What is the use of tracert command in networking?
Traceroute is a network diagnostic tool used to track in real-time the pathway taken by a packet on an IP network from source to destination, reporting the IP addresses of all the routers it pinged in between. Traceroute also records the time taken for each hop the packet makes during its route to the destination.
What does a tracert show?
A traceroute displays the path that the signal took as it traveled around the Internet to the website. It also displays times which are the response times that occurred at each stop along the route. If there is a connection problem or latency connecting to a site, it will show up in these times.
What is traceroute and how it works?
Traceroute ensures each hop on the way to a destination device drops a packet and sends back an ICMP error message. This means traceroute can measure the duration of time between when the data is sent and when the ICMP message is received back for each hop—giving you the RTT value for each hop.
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.

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 DNS?
Tracing the route is similar to the ping. Using this DNS tool, you send a packet of data to an internet host, and it gives you back a result for every hop your query makes in seconds.
Why does traceroute use UDP?
According to the Stevens (TCP/IP Illustrated) the traceroute program sends UDP packets to the destination host with an incremental TTL (1, 2, 3, etc) to get the intermediate hops info from the ICMP TTL EXPIRED messages.

What is the difference between tracert and ping?
The main difference between Ping and Traceroute is that Ping is a quick and easy utility to tell if the specified server is reachable and how long will it take to send and receive data from the server whereas Traceroute finds the exact route taken to reach the server and time taken by each step (hop).
How do I find my tracert IP address?
