Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Compared to IPv4 Header, IPv6 Headers are?
A
has less field thus allowing for more efficient packet handling
B
contains more fields and has more overhead
C
same number of fields and does the same operations as IPv4
D
none of the above
Explanation: 

Detailed explanation-1: -Difference between IPv4 and IPv6 header In IPv4, the header size can range from 20 to 60 bytes depending on the options field, but in IPv6, the header size is fixed at 40 bytes. But the main difference between both of them is the address size. IPv4 has 32-bit addresses so it can generate 4.29 * 10^9 addresses.

Detailed explanation-2: -The IPv6 header is a streamlined version of the IPv4 header. It eliminates fields that are either unneeded or rarely used, and it adds a field that provides better support for real-time traffic. Figure 4-3 shows the structure of the IPv6 header as described in RFC 2460.

Detailed explanation-3: -Unlike the IPv4 packet header, the IPv6 packet header does not carry IHL, identifier, flag, fragment offset, header checksum, option, or padding fields, but it carries the flow label field.
