What is the minimum length in hop by hop extension header in ipv6 ?
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 )
