Boeing Defence Australia — 2 prefixes (MA-L)

A MAC address beginning A4:29:83 or 98:49:E1 identifies hardware registered to Boeing Defence Australia (BDA), the Australian defence subsidiary of The Boeing Company. No public source ties either prefix to a specific named device model, so device class for both stays Unknown — what is confirmed is the registrant, not the product line.

BDA is a substantive, identifiable company rather than a bare single-OUI shell registration. It has operated in Australia since 1927, employs roughly 4,500 people across 13+ sites including RAAF Base Amberley and RAAF Base Williamtown, and is headquartered in Brisbane, Queensland — matching the registry's GPO Box 767 Brisbane address carried on both OUI rows.

Public BDA material names program-level platforms such as the E-7A Wedgetail, P-8A Poseidon, F/A-18F Super Hornet, and MQ-28 Ghost Bat, plus communications systems including the Wakulda air battlespace management system and the Currawong Battlespace Communications System. None of that material names either OUI specifically, so pinning a prefix to any one platform would be speculation.

Boeing Defence Australia is a separate legal entity from The Boeing Company's US OUI registrations (34:61:78, 00:06:F8, covered in the vendor-the-boeing entry). A 2023 LockBit/Citrix Bleed incident (CVE-2023-4966) documented for the US parent hit a different subsidiary, Boeing Distribution Inc., and is unrelated to this registrant or to either of these two prefixes.

Registration date

Unknown — IEEE's public OUI data carries no date field for either prefix; a third-party lookup site shows an unrelated "11 June 2016" value for A4:29:83 that is a database artifact, not an IEEE fact [Confirmed absence of IEEE date] — https://maclookup.app/search/result?mac=A4:29:83

Analyst note

Both OUIs confirm genuine Boeing Defence Australia-registered hardware, but the absence of a named device model means device class cannot be inferred from the registration alone.
