Determining the intermediate routers traversed involvesadjusting the time-to-live (TTL), aka hop limit, Internet Protocol parameter. Frequently startingwith a value like 128 (Windows) or 64 (Linux), routers decrement this and discard a packetwhen the TTL value has reached zero, returning the ICMP error message ICMP Time Exceeded.Tracert works by increasing the TTL value of each successive set of packets sent. The first set ofpackets sent have a hop limit value of 1, expecting that they are not forwarded by the firstrouter. The next set have a hop limit value of 2, so that the second router will send the errorreply. This continues until the destination host receives the packets and returns an ICMP EchoReply message.Trace route uses the returned ICMP messages to produce a list of hops (which usually consists
