&amp;#039;&amp;#039;&amp;#039;Speaker: Olaf Maennel, PhD - Loughboro University&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Topic: Security issues of IPv4-IPv6 transition&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Abstract&amp;#039;&amp;#039;&amp;#039;: &lt;br /&gt;
The growth of the Internet has made IPv4 addresses a scarce resource. Due &lt;br /&gt;
to slow IPv6 deployment, IANA-level IPv4 address exhaustion was reached&lt;br /&gt;
before the world could transition to an IPv6-only Internet. The &lt;br /&gt;
continuing need for IPv4 reachability will only be supported by IPv4&lt;br /&gt;
address sharing.  This lecture reviews ISP-level address sharing &lt;br /&gt;
mechanisms, which allow Internet service providers to connect multiple&lt;br /&gt;
customers who share a single IPv4 address. Some mechanisms come with&lt;br /&gt;
severe and unpredicted consequences, and all of them come with tradeoffs.&lt;br /&gt;
For example, will cyber-criminals now be untraceable, because content &lt;br /&gt;
providers (today) only log time and IP address of the attacker, but not&lt;br /&gt;
source ports?  Such and other questions will be discussed during the&lt;br /&gt;
lecture. &lt;br /&gt;
&lt;br /&gt;

Olaf Maennel is a lecturer at Loughborough University in the United&lt;br /&gt;
Kingdom since September 2009. Before that he was at Deutsche Telekom&lt;br /&gt;
Laboratories and at the School of Mathematical Science at the University&lt;br /&gt;
of Adelaide in South Australia. He received his Ph.D. (Dr. rer. net) from&lt;br /&gt;
the Technical University in Munich (Germany) in 2005. His research&lt;br /&gt;
interests are routing, network security, active measurements, next&lt;br /&gt;
generation internet technology, as well as configuration management.&lt;/div&gt;</summary>
