Advanced Technology Labs — 00:C0:FB (MA-L)

The OUI prefix 00:C0:FB is registered to "ADVANCED TECHNOLOGY LABS" at 22100 Bothell Highway S.E., Bothell, WA 98041-3003, US — a single 24-bit MA-L block (no MA-M or MA-S allocations). The Bothell address is the historical home of Advanced Technology Laboratories, Inc. (ATL), a manufacturer of high-end diagnostic medical ultrasound imaging systems founded in 1969 that entered the ultrasound market in the mid-1970s. This is a distinct entity from Lockheed Martin's Advanced Technology Laboratories (a defense R&D group in Cherry Hill, NJ) and is not a generic networking-hardware vendor. The MAC prefix would have identified ethernet-capable ATL ultrasound workstations and imaging equipment — the kind of DICOM/PACS-connected devices found on hospital networks. ATL was acquired by Royal Philips Electronics in 1998 for roughly $800 million and folded into Philips Medical Systems; the Bothell campus continued as Philips Ultrasound, so no independent ATL vendor entity or website survives today. Because IEEE publishes no assignment dates for OUI blocks, the "April 22, 1998" date shown by third-party lookup tools is a database artifact, not an IEEE fact, and is recorded here as Unknown. Any 00:C0:FB device still on a network is a 25-plus-year-old legacy medical imaging endpoint with no vendor support and should be treated as an unmanaged legacy device — DICOM/PACS imaging equipment is a documented healthcare attack surface industry-wide, though no ATL-specific CVEs were located.

IEEE assignment

00:C0:FB → ADVANCED TECHNOLOGY LABS, MA-L block [Confirmed] — the IEEE MA-L registry; maclookup.app/vendors/advanced-technology-labs

Registry / block size

MA-L (24-bit OUI; ~16.8M addresses); single block, no MA-M/MA-S entry [Confirmed] — the IEEE MA-L registry (no match in the IEEE MA-M registry / the IEEE MA-S registry)

Registry address / country

22100 Bothell Highway S.E., Bothell, WA 98041-3003, US [Confirmed] — the IEEE MA-L registry; cleancss.com/mac-lookup/00-C0-FB

Registration date

Unknown — IEEE publishes NO OUI assignment dates; third-party tools' "April 22, 1998" is a database artifact, not an IEEE fact [Unknown] — maclookup.app/vendors/advanced-technology-labs

Company identity

Advanced Technology Laboratories, Inc. (ATL) — diagnostic medical ultrasound imaging manufacturer, founded 1969, Bothell, WA; NOT Lockheed Martin ATL (Cherry Hill, NJ) [Confirmed] — fundinguniverse.com company history; lifesciencehistory.com

Device types

medical imaging equipment — ethernet/DICOM-capable diagnostic ultrasound systems and imaging workstations [Likely] — fundinguniverse.com; inferred from block class + product line. No specific device model independently tied to this OUI.

Company status

defunct as an independent entity — acquired by Royal Philips Electronics in 1998 (~$800M); folded into Philips Medical Systems / Philips Ultrasound; Bothell campus continued under Philips [Confirmed] — archive.seattletimes.com 1998-07-29 article; maclookup.app

Vendor website

none for the original ATL entity. Successor line is Philips Ultrasound (philips.com). The domain atlglobal.com exists but is an unrelated company. [Confirmed] — atlglobal.com (unrelated); philips.com

Security context

legacy medical ultrasound devices (1990s–early 2000s); if still networked, a high-risk unmanaged legacy endpoint with no vendor support. DICOM/PACS imaging is a documented healthcare attack surface (unauthenticated DICOM, patient-data exposure, unpatched devices) — industry-wide, no ATL-specific CVEs found.

Analyst note

a 00:C0:FB MAC reliably identifies legacy ATL/Philips-era medical imaging hardware for asset classification, but the line is long discontinued under the ATL name; treat such devices as obsolete medical endpoints requiring network isolation, not active vendor support.
