"Network Unreachable" for the sent
ECHO_REQUEST.
-R = Records the path. This includes the
RECORD_ROUTE option to the ECHO_REQUEST
packet, and displays the path buffer of the packet that
is returned. Note that due to the size of the IP header,
it can only contain eight paths. Most hosts ignore or
discard this option.
r = Bypasses the normal routing table and directly sends
packets to the host on the network. An error is
returned if the specified host does not exist on the
immediate network. This option is recommended
when there is no path information for a specific
interface and when pinging a local host through that
interface (e.g. when an interface is dropped by
routed(8)).
-s packetsize = Specifies the byte size of the outgoing
data. The default is 56 bytes, and when combined with
the 8-byte ICMP header data, the ICMP data becomes
64 bytes. The max value is 65468 bytes.
-T ttl = This uses the specified time-to-live.
-t tos = This uses the type of service specified in
hexadecimal.
-v = Enables verbose mode. This displays other
information in addition to the ECHO_RESPONSE of
the received ICMP packet.
-w maxwait = Specifies the wait time (seconds) for a
packet response before sending out the next packet.
The default is 10.0.

(1) There is no output if there is no response.
