Which is an IPv6 network header field?
The IPv6 header is more streamlined: it contains 8 fields, compared to IPv4’s 14 fields. version: 4 bits long, and corresponds to IPv4’s field of the same name. It indicates the receiver the IP version to expect. In case of IPv6 that is of course 6, making this field’s binary value 0110.
Which extension header does not include in IPv6?
IPv6 does not include a Header Length field because the IPv6 header is always a fixed size of 40 bytes. Each extension header is either a fixed size or indicates its own size. Replaced by the IPv6 Traffic Class field.

What are the differences between IPv4 and IPv6 header formats?

What is next header in IPv6?
Next Header is the field in the IPv6 header that informs IPv6 what is actually carried inside its payload. Some common values of the Next Header field is: 6 – TCP 17 – UDP 58 – ICMPv6 50 – IPsec ESP. The other fields in the IPv6 header is: Payload length: 16 bits field holding the total size of the payload above the IPv6 header. This
