Identifies the remote node to trace the route to by the hostname.
specifies the remote node using the node‘s logical host name which
must be resolved via DNS lookup.
<

Identifies the remote node to trace the route to by the IP address.
specifies the remote node using the node‘s assigned IP address
specified using the standard IPv4.
Specifies the number of UDP probe packets to send. The default is 3.
Indicates the packets for the tracing of the route should not be fragmented. If a packet
would require fragmenting then it is dropped and the ICMP response ―Unreachable,
Needs Fragmentation‖ is received.
