A host is sending 50 datagrams to another host. The identification number of the first datagram is 1044. You need to find the identification number of the last datagram.

In IPv4, the identification field increases by 1 for each datagram sent. It helps in reassembling fragments that belong to the same original packet.

So the sequence will look like this 1044, 1045, 1046, ... and so on

Now calculate the last one.

Last ID = First ID + (Number of datagrams - 1)  = 1044 + (50 - 1) = 1044 + 49 = 1093

Final Answer

• Identification number of last datagram = 1093

First ID	Total Datagrams	Formula	Last ID
1044	50	1044 + (50 - 1)	1093
