Lampuga GmbH holds a single IEEE MA-L block, 48:D4:75, registered at Werkstr. 11, Rastatt, Germany 76437 — confirmed against the IEEE registry (oui.csv line 48); no second block appears in the MA-M (mam.csv) or MA-S (oui36.csv) listings, so this is the company's only allocation. Lampuga made premium electric jetboards / motorized surfboards (the Lampuga Air and Boost), battery-powered recreational watercraft driven by a roughly 10 kW jet motor and throttled by a handheld Bluetooth pistol-grip remote tethered to the rider by a magnetic kill switch. The analyst-relevant quirk is that these boards have no Wi-Fi and no documented direct internet connectivity: the only wireless interface is the BLE throttle remote, so a 48:D4:75 OUI almost never surfaces in ordinary Wi-Fi or wired network scans. The company — a successor to Hamburg's Sashay GmbH — has since ceased operations and is defunct as of early 2026, with the website serving only a wind-down notice and no spare parts or new units available.
- IEEE assignment
- 1 prefix → "Lampuga GmbH" (48:D4:75), Werkstr. 11, Rastatt, Germany 76437 [Confirmed] — IEEE oui.csv (line 48), maclookup.app/vendors/lampuga-gmbh
- Registry / block size
- MA-L (24-bit OUI, ~16M addresses); 1 block [Confirmed] — IEEE oui.csv; not present in mam.csv (MA-M) or oui36.csv (MA-S)
- HQ / country
- Werkstr. 11, Rastatt, DE 76437 (IEEE registry address); company origin Hamburg, Germany (successor to Sashay GmbH) [Confirmed] — IEEE oui.csv; e-surfer.com/en/brands/lampuga/
- Company status
- DEFUNCT — filed for insolvency and ceased operations; confirmed defunct by early 2026 (site shows only a "ceased operations" notice; no new products or spare parts). Exact wind-down date not publicly confirmed. [Confirmed] — e-surfer.com/en/brands/lampuga/, lampuga.com/en
- Device types
- electric jetboard / motorized surfboard (recreational watercraft); models Lampuga Air (inflatable) and Lampuga Boost. ~10 kW electric jet motor, handheld BLE throttle remote, magnetic ankle kill switch.

- Lampuga Air, Lampuga Boost (electric surfboards) [Confirmed] — newatlas.com, e-surfer.com
- Verified prefix
- 48:D4:75 (MA-L) [Confirmed] — IEEE oui.csv, maclookup.app
- Connectivity / network exposure
- only wireless interface is a Bluetooth (BLE) handheld throttle remote; steering is purely physical (rider weight shift). No Wi-Fi and no documented direct internet connectivity. One operating-manual reference to a "Lampuga Rental" app suggests optional fleet/rental functionality, but no protocol or network-exposure detail is public. [Likely — single-source on the rental app] — lampuga.com/fileadmin/Lampuga_Manual_english.pdf, obmagazine.media/lampuga-just-ride/
- Security context
- no known CVEs, public vulnerability disclosures, or security research targeting Lampuga devices. The BLE throttle remote is the only wireless attack surface; generic BLE-remote risk classes (replay, spoofing) apply in theory to any BLE throttle, but no Lampuga-specific findings exist. Physical safety: magnetic kill switch plus overcharge/short-circuit/overcurrent battery protection. [Confirmed — absence of public findings] — obmagazine.media/lampuga-just-ride/
- Registration date
- Unknown — IEEE publishes NO assignment/registration dates in its OUI registry (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address). The "2023-06-07" first-seen value on maclookup.app is a third-party database artifact, not an IEEE fact, and is not attributed to IEEE here. [Confirmed] — IEEE oui.csv, maclookup.app/vendors/lampuga-gmbh
- IANA reference
- none — not applicable to an OUI entry; the blank IANA reference stays blank. [Confirmed]
- Related vendors
- Sashay GmbH (Hamburg predecessor entity)
- Analyst note
- A 48:D4:75 OUI identifies a Lampuga electric jetboard, but you will essentially never encounter it on a normal Wi-Fi or wired scan — the board's only radio is a BLE throttle remote, not a network interface. Treat the vendor as defunct: no firmware/spares support exists.
