Expert Solution

IPv6 Header Field :- IpV6 (Internet protocol version 6) is the latest version  of Internet Protocol, which is better than IP version 4 in terms of complexity and efficiency.

The value of the Header Extension Length field is the number of 8-byte blocks in the Hop-by-Hop Options extension header, not including the first 8 bytes. Therefore, for an 8-byte Hop-by-Hop Options header, the value of the Header Extension Length field is 0.The Hop-by-Hop header consists of a Next Header field, a Header Extension Length field, and an Options field that contains one or more options.

More information regarding IPv6 --

Headers field IPv6. :-

Version ( 4bits ) , Priority ( 8 bits) Traffic type , flow label ( 20 )

payload length (16 ), Next ( 8 ) reader , hop Limit ( 8)

Source Address (128 )

Destination Address ( 128 ).

BASE HEADER = 40 bytes (320 bits) And it is fixed.

E- xtension Headers :-

1. Routing Header (43 )

2.Hop by Hop Option (0)

3. Fragment header(44)

4. Authentication header(51)

5.Destination header (60)

6.Encapsulating Security Payload (50 )
