Are DHCP messages sent over UDP or TCP? 2. What is the link-layer (e. g., Ethernet) address of your host? 3. What values in the DHCP discover message differentiate this message from the DHCP request message? 4. What is the value of the Transaction-ID in each of the first four (Discover/Offer/Request/ACK) DHCP messages? What are the values of the Transaction-ID in the second set (Request/ACK) set of DHCP messages? What is the purpose of the Transaction-ID field?

1.) DHCP is sent over the message at UDP.

2.) The address of link-layer is Source: DellComp_4f:36:23 (00:08:74:4f:36:23)

3.) The message type of value to the discover message is 1, but the message type of value to the request packets is 3. This how you can be differentiate two.

4.) The Transaction ID in first four message is 0x3e5e0ce3

The transaction ID in second sets of messages is 0x257e55a3

The transaction ID is identifies if the message is a part of the set of the messages is related to the one transaction

Explanation:

DHCP is stands for the Dynamic Host Configuration Protocol which is the networks management protocol that is used on the UDP/IP networks where by the DHCP servers dynamically assign the IP address and the other networks configuration parameters to the each devices on the network so they can be communicate with the other IP network.
