Because each ping received a response, there was 0% packet loss. Command-line-based route tracing tools are usually embedded with the operating system of the end device. For all IPv6 addresses, the network ID is always the first ______ bits. During this process, the traceroute sends packets with Time To Live values that increases steadily from packet to packet; the process is started with Time To Live value of one. For each host in the processed path, the initial TTL for each host and the destination UDP port number for each packet sent are incremented by one. In addition to this, it will tell you how long each 'hop' from router to router takes. The first packet has a time-to-live (also known as TTL, or hop limit) of 1, the second packet has a TTL of 2, and so on. If DNS name servers are configured on the router, a route to them must also be present for DNS requests to be sent during traceroute.
