\subsection{Packet Headers}\cite{IPv6Pack77:online}
\wikicommons{Ipv6_header}
\begin{enumerate}
\item Version -- 1-byte field containing '6'.
\item Traffic Class -- 2-bytes hex notation for traffic class.
\item Flow label -- 5-bytes.
\item Payload length -- 4-bytes unsigned integer, which is the rest of the packet that follows the IPv6 header, in octets.
\item Next header -- 4-bytes selector. Identifies the type of header that immediately follows the IPv6 header. Uses the same values as the IPv4 protocol field.
\item Hop limit -- 32-bytes unsigned integer. Decremented by one by each node that forwards the packet. The packet is discarded if the hop limit is decremented to zero.
\item Source address -- 32-bytes.
\item Destination address -- 32-bytes. The intended recipient is not necessarily the recipient if an optional routing header is present.
\item \textbf{Version} -- 1-byte field containing '6'.

\subsection[EH]{Extension Headers}\cite{IPv6Pack77:online}
\begin{enumerate}
\item \textbf{Routing} -- Extended routing, such as IPv4 loose source route
\item \textbf{Fragmentation} -- Fragmentation and reassembly
\item \textbf{Authentication} -- Integrity and authentication, and security
\item \textbf{Encapsulating Security Payload} -- Confidentiality
\item \textbf{Hop-by-Hop options} -- Special options that require hop-by-hop processing
\item \textbf{Destination options} -- Optional information to be examined by the destination node
\end{enumerate}
