Quick traceroute
Quick traceroute traces the paths to target; it does not perform a scan on them. Traceroute is included in the Intense scan and is mostly used for network analysis.
As mentioned, the RTT marks the length of time it takes for a signal to be sent plus the length of time it takes for an acknowledgment of the same signal to be received. In Microsoft Windows, the traceroute is included by way of the tracert
command, which basically does the same on websites, tracking the response time redirections. Traceroute is often used by hackers, who use this tool to map the network nodes and get general information about the whole net architecture, making it easy to find and investigate a weak link on the network area. This is one of the reasons some webs block traceroute through utilities such as Firewall to prevent this easy network mapping on the whole net.
