Target IP address The IP address of the destination host.
Source address The IP address present on the router. This is used to
select an address that is not directly connected to the next hop.
Numeric display Disables nslookup on the IP address. Consequently, if
this option is chosen, only the IP address is displayed.
Timeout The threshold for response times for the returning error message.
Probe count The number of probes sent at each TTL level.
Minimum TTL The numerical value for the first TTL level.
Maximum TTL The maximum TTL value; an equivalent of 30 hops is
the default, and is the highest value possible.
Port Number The port number used by UDP that creates a port
unreachable error message.
Loose Source Routing Specifies nodes that must be included in the path
to the destination.
