I need in 10 min please

This is the structure of IP datagram format(IPv4): 0 0 4 8 12 16 19 24 31 Version Type of service identifier 4 (5 protocol Header checksum Source IP address Destination IP address options (1) Fill the blanks in the structure and explain what is the function of these fields(10 marks) (2) Suppose that there was an IP datagram whose value of TTL is 14.How many routers can it go through and explain why?(5 marks) (3) Suppose that there was an 6000 byte IP datagram.Obviously, it needs fragmentation and there is the structure of the datagram. Can you write out all the smaller IP datagram's structure?(15marks) Length=6000 ID=A Fragflag=0 Offset=0 This is the structure of IP datagram format(IPv4): 0 0 4 8 12 16 19 24 31 Version Type of service identifier 4 (5 protocol Header checksum Source IP address Destination IP address options (1) Fill the blanks in the structure and explain what is the function of these fields(10 marks) (2) Suppose that there was an IP datagram whose value of TTL is 14.How many routers can it go through and explain why?(5 marks) (3) Suppose that there was an 6000 byte IP datagram.Obviously, it needs fragmentation and there is the structure of the datagram.
