An IPv4 pаcket hаs the fоllоwing heаder infоrmation: Version = 4 IHL = 5 Total Length = 1000 bytes TTL = 1 Protocol = 17 Flags = MF set Fragment Offset = 185 Answer the following: a) What is the IP header size in bytes? b) How many bytes of data are carried in this IP packet? c) What happens when this packet reaches the next router? d) Is this packet the first fragment of the original packet? Justify your answer using the Fragment Offset field.
