In an IPv4 datagram, the M bit is 0, the value of HLEN is 10, the value of total length is 400 and the fragment offset value is300. The position of the datagram, the sequence numbers of the first and the last bytes of the payload, respectively are
- a)Last fragment, 2400 and 2789
- b)First fragment, 2400 and 2759
- c)Last fragment, 2400 and 2759
- d)Middle fragment, 300 and 689
Correct answer is option 'C'. Can you explain this answer?

In an IPv4 datagram, the M bit is 0, the value of HLEN is 10, the valu...
M = 0 meaning no more fragments after this. Hence, its the last fragment.
IHL = internet header length = 10 x 8 = 2400 B coz 4 is the scaling factor for this field.
Total Length = 2400 B
Payload size = Total length - Header length = 400-40 = 360B
fragment offset = = represents how many Bytes are before this. 8 is the scaling factor here.
the first byte # = 2400
Last byte # = 300 x 8 = 2400 B first byte # + total bytes in payload - 1 = 2400+360-1=2759
option C is correct
IHL = internet header length = 10 x 8 = 2400 B coz 4 is the scaling factor for this field.
Total Length = 2400 B
Payload size = Total length - Header length = 400-40 = 360B
fragment offset = = represents how many Bytes are before this. 8 is the scaling factor here.
the first byte # = 2400
Last byte # = 300 x 8 = 2400 B first byte # + total bytes in payload - 1 = 2400+360-1=2759
option C is correct

Understanding the IPv4 Fragmentation
To determine the position of the datagram and the byte sequence numbers, we need to analyze the provided parameters: M bit, HLEN, total length, and fragment offset.
Key Parameters
- M Bit (More Fragments): The M bit is 0, indicating that this is the last fragment.
- HLEN (Header Length): The value of HLEN is 10, which means the header is 10 * 4 = 40 bytes long.
- Total Length: The total length of the datagram is 400 bytes. This includes the header and the payload.
- Fragment Offset: The fragment offset is 300. This indicates the payload starts 300 * 8 = 2400 bytes from the beginning of the original datagram.
Calculating Byte Sequence Numbers
1. First Byte of Payload:
- The offset value of 300 tells us that the first byte of this fragment's payload starts at byte 2400.
2. Last Byte of Payload:
- The total length of the datagram is 400 bytes, and since 40 bytes are for the header, the payload size is 400 - 40 = 360 bytes.
- Thus, the last byte of this fragment's payload is:
- Starting byte (2400) + Payload size (360) - 1 = 2400 + 360 - 1 = 2759.
Conclusion
The analysis confirms that this is indeed the last fragment (M bit is 0), and the byte sequence numbers are:
- First Byte: 2400
- Last Byte: 2759
Thus, the correct answer is option C: Last fragment, 2400 and 2759.
To determine the position of the datagram and the byte sequence numbers, we need to analyze the provided parameters: M bit, HLEN, total length, and fragment offset.
Key Parameters
- M Bit (More Fragments): The M bit is 0, indicating that this is the last fragment.
- HLEN (Header Length): The value of HLEN is 10, which means the header is 10 * 4 = 40 bytes long.
- Total Length: The total length of the datagram is 400 bytes. This includes the header and the payload.
- Fragment Offset: The fragment offset is 300. This indicates the payload starts 300 * 8 = 2400 bytes from the beginning of the original datagram.
Calculating Byte Sequence Numbers
1. First Byte of Payload:
- The offset value of 300 tells us that the first byte of this fragment's payload starts at byte 2400.
2. Last Byte of Payload:
- The total length of the datagram is 400 bytes, and since 40 bytes are for the header, the payload size is 400 - 40 = 360 bytes.
- Thus, the last byte of this fragment's payload is:
- Starting byte (2400) + Payload size (360) - 1 = 2400 + 360 - 1 = 2759.
Conclusion
The analysis confirms that this is indeed the last fragment (M bit is 0), and the byte sequence numbers are:
- First Byte: 2400
- Last Byte: 2759
Thus, the correct answer is option C: Last fragment, 2400 and 2759.
