+\subsection{Retrieve MAC address}\label{retrieve-mac}
+
+To be able to connect to the device in a reliable and simple way using IPv6 the
+MAC address of the \texttt{wlan0} interface has to be retrieved and noted down.
+
+\begin{verbatim}
+ip link show wlan0  # MAC address right after 'link/ether'
+\end{verbatim}
+
+This MAC address can be converted to the corresponding IPv6 link-local address
+used for streaming audio to \texttt{soundbox}.
+
 \subsection{Package installation}
 
 soundbox requires packages from the Alpine Linux community package repository.
