traceroute <host>

Displays the route that packets take to a network host.

traceroute[ipv4|ipv6]host
ipv4
Displays the route that packets take to the IPv4 address of the host. This keyword is used when the host is specified as a host name rather than as an IP address.
ipv6
Displays the route that packets take to the IPv6 address of the host. This keyword is used when the host is specified as a host name rather than as an IP address.
host
A host that is the destination for the trace. The host is specified as a name (if DNS is being used on the network), an IPv4 or IPv6 address, or MAC address.

Operational mode

Use this command to perform a “traceroute” operation for a network host. This operation uses the IP protocol time-to-live (TTL) field and attempts to elicit an Internet Control Message Protocol (ICMP) TIME_EXCEEDED response from each gateway along the path to a host to track the route that a set of packets follows. It attempts to trace the route an IP packet follows to an Internet host by launching User Datagram Protocol (UDP) probe packets with a small time to live, then listening for an ICMP “Time exceeded” reply from a gateway.
