<h3>What is traceroute IP address?</h3>
Traceroute, also called tracepath or tracert, is a network tool used to determine the “path” packets take from one IP address to another.
It provides the hostname, IP address, and the response time to a ping. Enter the IP address that you want to lookup.
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.
