. So the traceroute just fills this flaw.The principle of traceroute is very very interesting, it receives the IP of the destination host, first sends a ttl=1 to the destination host (remember what TTL is?). UDP (the next to know what UDP is the packet), and after the first router receives the packet, the TTL is automatically reduced by 1, and the TTL becomes 0, the router will discard the packet, and at the same time produce a host unreachable ICMP datagram to the host. The host receives this d
