broad/multicast
proto, unroutable
The last part of each line lists the status of the packet.
TCP src= Displays the source and destination ports, the sequence number, the
acknowledgement number, and the window size of the packets in that TCP
packets.
UDP src= Displays the source and destination ports for the UDP packets.

IP Fragment States that it is a fragment and displays the unique number identifying the
fragment (Ident) and the oset (in 8-byte units) of this fragment (fragment oset)
from the beginning of the original datagram.
