Delta Telesystems Ltd. apparaît d'abord comme une énigme de routage: AS13259 est un réseau russe actif avec un enregistrement RIPE, des routes valides RPKI, des voisins publics et une surface de contact à Tioumen. Les preuves commerciales changent ensuite la question. Oborona.
Delta Telesystems Ltd. first appears like a routing puzzle: AS13259 is a live Russian network with RIPE registration, RPKI-valid routes, public neighbours and a Tyumen contact surface. The business evidence then changes the question. Oborona.net presents the same operator as a local home internet, IPTV and business-connectivity provider in Tyumen, with a visible office, tariffs, customer contracts, support numbers, company card, licences and third-party listings. The economic issue is therefore not whether the name exists in a registry. It is how much value should be assigned to a small telecom identity when the public proof is real but still leaves subscriber counts, revenue capture, licence continuity, upstream economics and customer concentration partly unresolved.
