Explanation:
Detailed explanation-1: -The main difference between IPv4 and IPv6 is the address size of IP addresses. The IPv4 is a 32-bit address, whereas IPv6 is a 128-bit hexadecimal address. IPv6 provides a large address space, and it contains a simple header as compared to IPv4.
Detailed explanation-2: -The correct answer is option 4. In IPv6, the fragmentation fields from IPv4’s base header segment have been transferred to the fragmentation extension header, and hence the given statement is right. Both IPv4 and IPv6 have the same authentication header, but IPv6 has a new authentication extension header.
