My understanding of this presentation is that the NSA is continuously mapping the internet via open source and commercial information, and also running huge numbers of traceroute requests from servers located all over the world. The classification level of U//FOUO (Unclassified / For Official Use Only) of most of the items suggests that this information is intended to be shared with various other government entities, such as law enforcement agencies. This might allow for more accurate location of a target IP address than would otherwise be possible.
