Fragment offset values are always multiples of which number?

• A. 4
• B. 16
• C. 8
• D. 2

Answer: (C)

Fragment offset is defined in units of eight bytes. When a datagram is fragmented, every fragment must start at an 8-byte boundary in the original payload, so the actual byte position where a fragment begins is a multiple of eight. The value stored in the header tells how many 8-byte blocks into the datagram this fragment starts, and you multiply by eight to get the byte offset. For example, an offset value of 3 means the fragment starts at byte 24. This 8-byte alignment is why the correct choice is eight.
