PLEASE answer with clear and easy to understand!

Refer to the following Figure 5. 10.168.10.129/26 10.168.10.65/26 B2:B2:B2:B2:B2:B2 10.168.10.130/26 10.168.11.65/26 C3:C3:C3:03:C3:C3 10.168.10.99/26 A1:A1:A1:A1:A1:A1 10.168.11.88/26 D4:04:04:04:04:04 Figure 5 (a) Let Host A is sending an IP packet to Host B, determine (i) source IP address. (ii) destination IP address, (iii) source MAC address, and (iv) destination MAC address of the IP packet for the following cases: In the frame from Host A to R2. In the frame from R1 to Host B. (b) Let say Host A did not know the MAC address of the interface of R2. Briefly discuss the additional steps needed before Host A is able to send the IP packet to R2. (c) A cyclic redundancy check (CRC) error detection scheme is used in Figure 5. (i) Given a 10-bit sequence 1101110001 and a divisor of 1010, find the CRC. (ii) Given a remainder of 110, a data unit of 10110011, and a divisor of 1001; analyse the data received
