After the per$-$packet pcap header is the tra$$c data. Improve your callback to decode IP packets. Your callback should obtain the source and destination IP addresses, the protocol $($e$.$g$.$TCP$,$UDP$,$ ICMP, etc$),$source and destination transport port $($where applicable$),$etc$.$

Several questions ask for an answer in the form of a distribution. Please note that a distribution must represent each value in the form of a fraction or percentage of the total. Answer the following questions:

$3.$ How many IPv$4$ packets does the trace contain?

$4.$ Estimate the size of the telescope $($i$.$e$.,$ how many addresses does it monitor$).$ Provide your estimate in $$stroke$$ notation, e$.$g$.,/8.$

$5.$ What is the packet protocol distribution? $($A table showing the $5$ top protocols and their respective contributions is $$ne$.)$

$6.$ Plot a histogram of the packet size distribution.
