The Boeing Company — 2 prefixes (MA-L)

A MAC address starting with 34:61:78 or 00:06:F8 belongs to The Boeing Company, the aerospace and defense manufacturer, seen on networking equipment registered to Boeing corporate facilities rather than to any single named consumer product line.

The two prefixes trace to two different Boeing facility addresses in the IEEE registry: 34:61:78 to 325 James S. McDonnell Blvd, Hazelwood, MO — the former McDonnell Douglas manufacturing campus that became a Boeing site after the 1997 McDonnell Douglas merger — and 00:06:F8 to 5731 W. Las Positas Blvd., Pleasanton, CA. Both addresses independently corroborate as real, active Boeing locations.

Boeing is an unambiguous, publicly traded (NYSE: BA) company with a large public web presence, so this is not a bare shell registration. The IEEE registry also carries several separately-named Boeing-affiliated registrant rows — Boeing Defence Australia, BOEING DEFENSE & SPACE, BOEING, Boeing India Private Limited, and BOEING SSG — which are distinct registrations under their own prefixes and are not part of this entry's prefix list, but they corroborate a large multi-facility organization.

No vendor documentation, product datasheet, or packet-capture writeup was found tying either specific prefix to a named device model. Boeing's public avionics-networking material (AFDX/ARINC 664, Aircraft Interface Device) is real and well documented, but none of it cites either of these two OUIs by name, so device type is recorded as Unknown rather than inferred.

No malware, botnet, or CVE association was found tied to either OUI prefix itself. At the corporate level, Boeing Distribution Inc. — a separate Boeing parts-distribution subsidiary — was hit by a LockBit 3.0 ransomware attack in October 2023 that exploited the Citrix Bleed vulnerability (CVE-2023-4966); this is general corporate cybersecurity history unrelated to these MAC prefixes and should not be read as identifying traffic from Boeing-prefixed devices.

Analyst note

a MAC in 34:61:78 or 00:06:F8 identifies genuine Boeing-registered hardware, but the device class is not established from public sources — do not infer a specific product or use OUI alone for asset classification here; the other Boeing-named registry rows are separate registrations and do not share these two prefixes.
