Next Header value for the IPv6 fragment header?

Next Header value for the IPv6 fragment header?

• A. 0x3c (60)
• B. 0x22 (34)
• C. 0x01 (1)
• D. 0x2c (44)

Answer: (D)

In IPv6, the Next Header field indicates what type of header comes next in the chain. Each header type has a numeric value, and the Fragment header is assigned the value 44 (0x2c). So when the IPv6 header shows that the next header is a Fragment header, it uses 44. After the Fragment header, its own Next Header tells what follows (such as TCP or UDP).
