Autonomous system 211381, based in Oude Meer in the Netherlands, was registered on 29 September 2026. Security researchers on Mastodon flagged the fresh allocation as part of a routine Shodan watch, a practice where infosec observers track newly announced networks for early signs of hosting infrastructure, spam operations or other activity worth monitoring.
Why now: Infosec communities routinely monitor newly registered ASNs to spot infrastructure before it is used.
