Vencer Co., Ltd. — 2 prefixes (MA-L)

Vencer Co., Ltd. (晶綸股份有限公司) is a Taiwan-based consumer-electronics maker that holds two distinct IEEE MA-L blocks under the exact same legal name: 00:1B:DC and 88:D1:99. The two registrations carry different Hsi-Chih/New Taipei City addresses, consistent with a company that moved over its lifetime rather than two unrelated firms — the older 00:1B:DC block lists a Taipei address with the legacy postal code 221, and 88:D1:99 lists the renamed "New Taipei City" (22101) address that reflects Taiwan's 2010 county-to-city administrative change. The company was founded in January 2007 and specializes in Bluetooth wireless peripherals: USB Bluetooth dongles and adapters, a Bluetooth presenter/clicker, a mono headset, a stereo receiver dongle, and Hi-Res headphone amplifiers. Device-type is corroborated from two independent angles — the vendor's own site and HKTDC sourcing listing, and FCC filings under grantee code VHV (8+ distinct products, roughly 2008–2016+). Holding two separate MA-L blocks is itself a substance signal; single-product shell registrants rarely acquire more than one. No notable public security or abuse history turned up for either OUI, which for a small consumer-accessory vendor reads as "nothing found," not a clean bill of health.

Analyst note

the slug "vendor-vencer" maps to a single legal entity that owns both blocks; a page should surface both 00:1B:DC and 88:D1:99 rather than picking one.
