Nolan wants to know if he can use a VPN to make networks think he's somewhere else. Leo says yes, that's pretty much what the VPN does. Some people use VPNs to stream other countries' video streams for that very reason. VPNs have a client and a server. The client goes on the users' PC, while the server is somewhere else. Users then log into the VPN, and the IP address will be wherever they connect to it. But there is a catch. VPN providers use a pool of IP addresses that they own, and they identify them as VPN addresses. So while it can make anyone think that a user is somewhere else, it also tells them that it's a VPN, so they don't trust that as being factual.
