See the Wikipedia article Turedo tunneling for more information. During the transition period from IPv4 to IPv6, a temporary method called Teredo tunneling is being used to "repackage" data packets and permit communication between IPv4 and IPv6 devices (e.g., using the 6to4 protocol for tunneling IPv6 data to a device with a IPv4 address) - hence the "Pseudo-Interface" in your security history messages. See the Wikipedia article IPv6 for more information. To solve that problem, a new protocol call IPv6 has been developed than uses 128-bit addresses with the format of four hexadecimal digits separated by colons (e.g., fe80::12ac:fe44:192a:14cc) that allows many more devices to be connected.

The rapid growth of the Internet means that there will not be enough free IPv4 addresses to connect new devices in the near future. IPv4 addresses that most people are familiar with (e.g., 172.16.0.0) are 32-bit address that allow a maximum of just over 4 billion different addresses. Internet Protocol (IP) is a communications protocol that allows identification and location of computers on networks and routing of traffic across the Internet.
