ADB holds 3 MA-L blocks (about 50.3 million addresses) registered as "Advanced Digital Broadcast SA" at Route de Crassier 21, B2, Eysins, Switzerland. Verified samples are 68:63:59, C4:77:AF, and 20:83:F8. These OUIs appear on set-top boxes (cable/satellite/IPTV/DVB), broadband gateways, and DSL/fiber residential gateways, supplied to operators and ISPs and typically carrier-branded. ADB was founded in 1995, IPO'd on the Swiss exchange in 2005, went private in 2015, and acquired Pirelli Broadband Solutions in 2010; it maintains R&D in Poland and Italy and operations in Taipei, Taiwan. The corporate lineage is notable: ADB / Advanced Digital Broadcast is the parent lineage of SmartRG (covered in the prior batch), and SmartRG was later acquired by ADTRAN — so ADB, SmartRG, and ADTRAN form a lineage chain. The key analyst point combines the brand mapping with an operator/ISP-supplied-gear angle: an ADB OUI most often appears on a carrier-deployed STB or residential gateway, branded by the operator, not by ADB. For triage, an ADB OUI (68:63:59, C4:77:AF, 20:83:F8) in a home or ISP network is CPE — a set-top box or broadband gateway, usually carrier-branded despite ADB being the manufacturer.
