\subsection{Address Types}
\subsubsection{Link-Local}
\begin{itemize}
\item \itemhead[]{Link-Local}
\item Address assigned from the \texttt{fe80::/10} prefix.
\item Either derived with the EUI-64\footnote{The EUI-64 involves the MAC address and injecting fffe into the middle making it 64 bits and using this as host bits} method or randomly selected. Then assigned after \gls{dad} has been run on the network segment.
\item \itemhead[]{Unique Link Local}\cite{wiki:Unique_local_address}
\begin{itemize}
\item Address assigned from the \texttt{fe80::/10} prefix.

\item \itemhead[]{Unique Link Local}\cite{wiki:Unique_local_address}
\begin{itemize}
\item Defined as block \texttt{fc00::/7}. See \rfc{4193}.
\item \gls{ula} is \glspl{ip6} counter-part to \glspl{ip4} \rfc{1918} address space.
\item Only usable within a private network.
\item Divided into 2 /8 \gls{ip6} blocks.
\begin{enumerate}
\item \texttt{fc00::/8} -- Not \textit{yet} officially allocated/defined by the \gls{ietf}.
\item \texttt{fd00::/8} -- Defined as /48 prefixes. The last 40 bits is randomly generated and appended to the first 8 significant bits {\small (i.e. \texttt{0xFD} aka. \texttt{11111101})}.
\end{enumerate}
\end{itemize}
\item \itemhead[]{Solicited-node multicast address}\cite{wiki:Solicited-node_multicast_address}
\begin{itemize}
\item Consist of the prefix \texttt{ff02::1:ff00:0/104} for the first 104 bits.
\item The last 24 bits represents the target address within the prefix.
\item Solicited-node multicast address is segment only traffic. I.e. the traffic does not flow \textit{between} \gls{l3} \gls{ip} segments.
\item Used in combination with \gls{nd} to replace \glspl{ip4} \gls{arp} functionality.
\end{itemize}

\item \itemhead[]{Global Addressing}
\item \itemhead[]{Solicited-node multicast address}\cite{wiki:Solicited-node_multicast_address}
\begin{itemize}
\item Address types
\begin{itemize}
\item Unicast: Identifies each \gls{nic}.
\item Anycast: Identifies a group of \glspl{nic} belonging to the same group and providing the same services/content/applications. Nearest one to source is used.
\item Multicast: Used to deliver content to multiple \glspl{nic} at once. Traffic is a single flow from the source (i.e. not multiple unicast streams).
\item Broadcast: \textit{Not} implemented. Replaced by use of multicast groups.
\end{itemize}
