Quiz 8 1. Print the first fragment of the fragmented IP datagram. What information iscontained in the IP header that indicates fragmentation of the datagram has occurred? What information is contained in the IP header that indicates whether this is the first fragment or a subsequent fragment? What is the length of the IP datagram? • It is already fragmented because the flag is more fragment. The first one is known because the fragment offset is still 0. 2. Print out the second fragment of the fragmented IP datagram. What information in the IP header indicates that this is not the first fragment? Is there a continuation fragment? How do you know? • Because the fragment offset is 1480, it indicates that this is not the first fragment. There are no further fragments because the more fragment flag is not set. 3. What fields have changed in the IP header in the first and second fragments? • The fields that change are flags, header checksum, total length and fragment offset.
