This may be accomplished by directing the network actor to request and/or access a network-segment identification resource which may, in some embodiments, be stored in another region of the global network. The system may include links and/or other identifiers pointing the network actor to one or more network-segment identification resources. The network actor may access the network-segment identification resources using the links or identifiers, and the system may use information about the request for the network-segment identification resource to determine whether the network actor is associated with multiple source addresses."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting virtual private network usage","description":"According to some aspects described herein, a system may determine whether a network actor appears to be using an intermediary such as a VPN and/or proxy server.
