 \section{\label{introduction:motivation}Motivation}
 The Internet has almost completely run out of public IPv4 space. The
-Regional Internet Registries
+5 Regional Internet Registries (RIRs) report IPv4 exhaustion world wide
 (\cite{ripe_exhaustion},
 \cite{apnic_exhaustion},
-\cite{lacnic:_ipv4_deplet_phases}
+\cite{lacnic:_ipv4_deplet_phases},
-is common knowledge
+\cite{afrinic:_afrin_ipv4_exhaus},
+\cite{arin:_ipv4_addres_option}) and LACNIC project complete
+exhaustion for 2020 (see figure \ref{fig:lacnicexhaust}).

+On the other hand IPv6 adoption grows significantly, with at least
+three contries (India, US, Belgium) surpassing 50\% adoption
+(\cite{akamai:_ipv6_adopt_visual},
+\cite{vyncke:_ipv6_deploy_aggreg_status}).

+\cite{cisco:_ipv6}). Traffic from Google users reaches almost 30\% as
+of 2019-08-08 (\cite{google:_ipv6_googl}).
