Answer 1

1. What information (given as info) is on the ARP request packet.

In ARP request packet ("who is X.X.X.X tell Y.Y.Y.Y', where X.X.X.X and Y.Y.Y.Y are IP addresses) is sent using the Ethernet broadcast address, and an Ethernet protocol type of value 0x806. Since it is broadcast, it is received by all systems in the same collision domain (LAN). This is ensures that is the target of the query is connected to the network, it will receive a copy of the query

2. What is the meaning of the request information

Request Information is When Source device wants to communicate with some other device on a local network (for example on an Ethernet network that requires physical addresses to be known before sending packets).

The sending device uses ARP to translate IP addresses to MAC addresses. The device sends an ARP request message containing the IP address of the receiving device. All devices on a local network segment see the message, but only the device that has that IP address responds with the ARP reply message containing its MAC address. The sending device now has enough information to send the packet to the receiving device.

3. What is the destination MAC address

For a ARP request,destination MAC address is the Ethernet broadcast address (FF:FF:FF:FF:FF:FF)

4. What is the source MAC address

For a ARP request, source MAC address is the MAC address of the host sending the ARP request.

5. What is the destination IP address

 The IP address of the host receiving the ARP request.

6. What is the source IP address

 The IP address of the host sending the ARP request.

7. What information (given as info) is on the ARP response packet.

In ARP response packet (who is "X.X.X.X is hh:hh:hh:hh:hh:hh", where hh:hh:hh:hh:hh:hh is the Ethernet source address of the computer with the IP address of X.X.X.X). This packet is unicast to the address of the computer sending the query (in this case Y.Y.Y.Y). Since the original request also included the hardware address (Ethernet source address) of the requesting computer, this is already known, and doesn't require another arp message to find this out.

8. What is the meaning of the response information

Response Information is When Target device that matches all the Information that are needed for the source device to be communicate matches and available.Now Recieve Device gives acknowledgement to the Sender to Connect with it.

9. What is the destination MAC address

For ARP reply,destination MAC address is the MAC address of the host that sent the ARP request 

10. What is the source MAC address

For ARP reply, source MAC address is the MAC address of the host replying to the ARP request 

11. What is the destination IP address

The IP address of the host receiving the ARP reply.

12. What is the source IP address

 The IP address of the host sending the ARP reply.
