The only use that comes to mind for me is in making the "rough cut" on determining the location of a VOIP user dialing 9-1-1 from a new location not shared with his VOIP provider--
Every VOIP packet contains a source and destination IP addresses, which identifies a provider / Country / City / and user account. The "location" will ALWAYS be the last router in the ISP's network connecting to the user.
I still don't get the point of this
