IPv6 base header
Description
Header that is processed by all hops in the path of a
packet. When present, the hop-by-hop options header
always follows immediately after the basic IPv6
packet header.
Header that can follow any hop-by-hop options
header. The header is processed at the final destination
and at each visited address specified by a routing
header. Alternatively, the destination options header
can follow any Encapsulating Security Payload (ESP)
header. The destination options header is processed
only at the final destination.
Header that is used for source routing.
Header that is used when a source fragments a packet
that is larger than the Maximum Transmission Unit
(MTU) for the path between itself and a destination.
The Fragment header is used in each fragmented
packet.
Headers that are used inside a packet to transport the
data. The two main transport protocols are TCP and
UDP.
