\begin{itemize}
\item A network of items — each embedded with sensors — which are connected to the Internet. \footfullcite{minerva2015towards}

\begin{itemize}
\item 1969 - ARPANET
\item 1980's - Commercial Internet services
\item 1993 - Global Positioning System
\item 2017 - IPv6 Standard
\end{itemize}
\vspace*{10pt}
IPv6 - 128 bit addresses as opposed to 32 bit addresses in IPv4 \\
$2^{128} = 3.4 * 10^{38}$ addresses \\
