![]() The probe answers come from different gateways, the address of each responding system will be printed. The address can be followed by additional information when requested. Is printed showing the ttl, address of the gateway and round trip time of each probe. Three probes (by default) are sent at each ttl setting and a line (or TCP reset), which means we got to the "host", or hit a max (which defaults to 30 hops). We start our probes with a ttl of one and increase by one until we get an ICMP "port unreachable" Listening for an ICMP "time exceeded" reply from a gateway. ![]() This program attempts to trace the route an IP packet would follow to some internet host by launching probe packets with a small ttl (time to live) then The specified size can be ignored in some situations or increased up to a minimal value. ![]() Packet (default 60 bytes for IPv4 and 80 for IPv6). The optional packet_len'gth is the total size of the probing The only required parameter is the name or IP address of the destination host. Traceroute6 is equivalent to traceroute -6 It utilizes the IP protocol's time to live (TTL) field andĪttempts to elicit an ICMP TIME_EXCEEDED response from each gateway along the path to the host. Traceroute tracks the route packets taken from an IP network on their way to a given host. ![]()
