All fragments of the same packet will share the same value in which IPv4 header field?

All fragments of the same packet will share the same value in which IPv4 header field?

• A. Flags
• B. ECN
• C. Identification
• D. Version

Answer: (C)

In IPv4, when a packet is fragmented during transmission, all the fragments retain common attributes that allow the receiving device to reassemble them into the original packet. The Identification field in the IPv4 header plays a crucial role in this process. Each fragment of a packet generated from a single datagram shares the same Identification value. This unique identifier allows the destination host to correctly reassemble the fragments in the correct order, even if they arrive out of sequence. The Identification field helps distinguish between different packets that may be fragmented during transit. Each packet has a unique value that differentiates it from other packets, which is essential when multiple packets are being sent over the network. Therefore, upon receipt, the receiving device can easily identify and correlate all fragments of a specific packet by using the same Identification value, facilitating smooth reassembly. In contrast, other fields such as Flags, ECN (Explicit Congestion Notification), or Version may not necessarily carry the same value across all fragments generated from the original packet. Flags indicate control information specific to each fragment, ECN is utilized for traffic management, and the Version field denotes the format of the IPv4 packet. Hence, these fields may differ or serve different functions and do not have the same significance when it comes to
