As my colleague has already mentioned, this is not new. CSE has to take these kinds of unknown entities and elements of information and try to flesh them out to understand exactly what we're dealing with. It could be as simple as a Google search. It could be looking or working with other databases that are out there that might help us contextualize this. In the case of an IP address, there are registries that exist online that tell you where an IP address is geographically registered.
