Carrier-Grade NAT

The use of large-scale IP address sharing technologies (such as "Carrier-Grade NAT" and "A+P") present a challenge for law enforcement agencies due to the fact that the information required to attribute criminal activity based on IP address is not commonly recorded. Specifically, incoming source port information is not routinely logged by Internet-facing servers. The absence of this information means that it is becoming increasingly difficult for law enforcement agencies to identify suspects in criminal activity online. FTR Solutions has been working for some time to address this challenge.

This page provides references to the various publications and other resources that have been produced as part of that initiative.
