Experience in IPv6 use as support for the Internet of Things

Abstract

The purpose of this experiment held at the Faculty of Applied Sciences (FCA) of the State University of Campinas (UNICAMP) was to set up on the data network the dual-stack Internet Protocol version 4 (IPv4) and the Internet Protocol version 6 (IPv6) on servers and workstations. The experiment was carried out by setting up a tunneling server to encapsulate the IPv6 addresses within IPv4 tunnels, since we do not have native connection of version 6 addresses. Both the outgoing and the incoming traffic were controlled through a firewall in the tunnel for providing better safety services. The main ones (such as name resolution, sending and receiving email, and web pages) were configured in order to understand the impact caused by the integration of these kinds of traffic on the network. The result was a higher speed in IPv6 traffic compared to IPv4, and friendly coexistence between these two versions and protocols. Although it is not possible to set up only the IPv6 on the data network, this experiment was valuable to better understand the operation of this new protocol and the needs concerning software and hardware
