DHCP server in the following way:

Packet$-1.$ DHCP Discover $-$ Client broadcasts a discovery request to all devices on the network in an

attempt to reach a DHCP server.

Packet$-2.$ DHCP Offer $-$ An IP lease is offered to the client by the DHCP server.

Packet$-3.$ DHCP Request $-$ The client then requests an IP lease from the server.

Packet$-4.$ DHCP ACK$($knowledge$)-$ Lastly the server acknowledges an IP lease.

Now the device has been assigned a leased IP address.

Figure $9$ The DHCP client & server packet exchange showing how an IP address is assigned via DHCP$.$

As you will see, the $4-$step process that assigns the dynamic IP address to the device is listed in the four

packets in Wireshark. Analyze the four packets in this packet capture and answer the questions below.

Question $4\mathrm{.}4\mathrm{.}1$: After looking at the packets, what are the $4$ phases of a DHCP request?

Question $4\mathrm{.}4\mathrm{.}2$: Out of the two transport protocols $($TCP or UDP$),$ which is used for DHCP$?$ Why do you

think this is$?$

Question $4\mathrm{.}4\mathrm{.}3$: What incoming server port does DHCP rely on to receive requests? $($Hint: Look at the

Packet Details Pane.$)$

End of Lab Questions:

From our slammer.pcap file, what is the destination IP of the packet?

What is DNS$?$

What port does DNS listen on$?$

Who is the DHCP Discover sent to$?$ Who is the intended recipient?
