What is Tracert?

Although the exact description of Tracert is complicated, it is actually an inquiry software command. The tracert command allows us to see the network elements (such as router and server) that the packets we send while reaching a server and how long it has spent on each network element or errors, if any. Most of all, it helps to find the errors that occurred during the transfer. Coming to the main definition, Tracert is a network tool that indicates how long the access between the target IP / domain name and your computer takes place over which IPs. In other words, it is a network diagnostic tool used to trace the path of data from source to destination. It shows not only the elapsed time but also the route the data takes between the target computer and the source computer, and how much delay it takes to pass through these routes. Traceroute uses Internet Control Message Protocol (ICMP) echo packets, which are values ​​of the lifetime variable known as TTL. The response time of each tab is calculated. To ensure accuracy, each tab is queried multiple times to better measure the response of that tab. Network devices, which are called Routers, that provide the distribution of packets in the internet, transmit the packet to the next network element, minimizing the TTL (time-to-live) value in the packet. The reason for this is that, if there is any, packets are prevented from being routed indefinitely or more than necessary in loops within the network. Typically a high value of 64 is assigned by clients for the TTL duration. If a total of 64 network elements do not change until the package reaches its destination, it will decrease by one and reach its destination safely. In case there are indeed more than 64 elements in the network, the Router, which receives the packet with a TTL value of 1, notifies the original sender of the packet that it has thrown it as it cannot send the packet to the next stop. For this, it sends the ICMP Type 11 message called Time Exceeded so that the source that sent the packet to the network is aware of the situation.
