These are the exit addresses of a commercial VPN service with customers everywhere. An address on this list says that a connection came through Astrill, which DPRK IT workers are documented to favour; it does not say who was behind the connection, and the great majority of traffic through these exits is ordinary customers. Treat a match as a reason to look at the account behind it, not as evidence about the person. The list is a snapshot of the addresses active on 19 December 2024; VPN exits are reassigned over time, so an address here may since have been returned to its hosting provider and given to someone else. The list is Spur's and is carried here as published.
