ADFweb.com S.r.l. — 10:64:E2 (MA-L)

A MAC address starting with 10:64:E2 belongs to ADFweb.com S.r.l., an Italian industrial-automation hardware manufacturer, and is typically seen on protocol-converter gateways, industrial I/O modules, and Ethernet-capable field devices rather than consumer electronics.

ADFweb is headquartered at Strada Nuova 17, Mareno di Piave, Treviso, Italy (31010). The company designs and sells industrial protocol converters/gateways, intelligent I/O modules, signal converters, and industrial radio devices (LoRaWAN, wireless M-Bus) supporting Modbus, Modbus TCP, PROFINET, PROFIBUS, EtherNet/IP, CANopen, J1939, BACnet, MQTT, OPC UA, and IEC 61850, serving factory automation, building automation, and energy/IoT sectors.

Corroboration beyond the vendor's own site includes a listing as a member company on the Modbus Organization's official site, and presence in independent business directories (Dun & Bradstreet, Bloomberg, Creditsafe, ZoomInfo) that carry a matching registered address and a 2004 incorporation year. This is an identifiable, operating company, not a bare shell registration.

Only one OUI assignment is found for this vendor: 10:64:E2 (MA-L). A grep of the repo's own the IEEE MA-S registry and the IEEE MA-M registry registries turned up zero additional matches for "adfweb," and no other MA-M or MA-S blocks were located via web search either, so this appears to be a single-block registrant.

No CVE naming ADFweb is recorded in the NVD as of an August 2026 search, and no CISA/ICS-CERT advisory names the vendor as of the same search.
