BAE Systems — 12 OUI assignments (MA-L / MA-M / MA-S)

A MAC address beginning with BC:D7:67, CC:3F:EA, 18:F9:C4, 00:0B:F3, or 00:90:25 belongs to BAE Systems, a global defense, aerospace, and security contractor with roughly 110,000 employees across 40+ countries. The IEEE registry itself does not indicate which specific product line an address maps to — only the registering corporate entity and address.

BAE Systems holds 12 confirmed IEEE assignments spread across three registry tiers: 5 MA-L (24-bit) blocks, 1 MA-M (28-bit) block, and 6 MA-S (36-bit) sub-blocks. The registrations are split across at least seven corporate addresses in the UK, US, and Australia, reflecting divisional structure — BAE Systems, Inc, BAE Systems Australia (Electronic Systems) Pty Ltd, and BAE Systems Surface Ships Limited each appear as separate registrants rather than one centralized allocation.

BAE Systems operates across Air, Land, Sea, Space, and Cyber domains — fighter jets, naval combat systems, armored vehicles, satellites, and cyber consultancy. No specific device model, datasheet, or advisory could be tied to any individual prefix in this research pass; device-type attribution beyond "BAE Systems corporate/defense hardware" should be treated as Unknown until a follow-up pass ties a prefix to a named product.

As with most IEEE registrants, the public OUI data (the IEEE MA-L registry / the IEEE MA-M registry / the IEEE MA-S registry) carries no assignment-date field, so no registration date can be attributed to any of these prefixes. Any third-party "date registered" figure for a BAE Systems block would be a database artifact, not an IEEE fact.

IEEE assignment

BC:D7:67, CC:3F:EA, 18:F9:C4, 00:0B:F3, 00:90:25 (MA-L) → BAE Systems / BAE Systems, Inc / BAE Systems Australia (Electronic Systems) Pty Ltd [Confirmed] — local IEEE MA-L registry mirror (the IEEE MA-L registry)

Registry / block size

5 MA-L (24-bit) + 1 MA-M (28-bit) + 6 MA-S (36-bit) = 12 confirmed assignments [Confirmed] — local IEEE registry mirrors (the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry). NOTE: IEEE's public OUI data publishes NO assignment/registration date; any third-party "date registered" is a database artifact, not an IEEE fact.

HQ / country

no single HQ address — registrations span Waterside House, Surrey Research Park, Guildford, Surrey, GB GU2 7RQ; Broad Oak, Portsmouth, Hampshire, GB PO3 5PQ; 21 Continental Boulevard, Merrimack, NH 03054, US; 65 Spit Brook Rd, Nashua, NH 03060, US (registry text rendered "Spir Brook Rd"); 1098 Clark Street, Endicott, NY 13760, US; 150 Parish Drive, Wayne, NJ 07470, US; 6500 Tracor Lane, Austin, TX 78725, US; 2 Second Ave, Mawson Lakes, SA 5095, AU

Verified sample prefixes (MA-L, confirmed to BAE Systems entities)

BC:D7:67 (Guildford, UK); CC:3F:EA (BAE Systems Inc, Endicott, NY); 18:F9:C4 (Merrimack, NH); 00:0B:F3 (Austin, TX); 00:90:25 (BAE Systems Australia (Electronic Systems) Pty Ltd, Mawson Lakes, SA) [Confirmed] — local IEEE MA-L registry mirror

MA-M / MA-S prefixes (exact hex values, verified against the registry mirror)

94:05:BB:E/28 (MA-M, Merrimack NH); 8C:1F:64:55:6/36 (MA-S, Nashua NH); 70:B3:D5:AF:C/36 (MA-S, Endicott NY); 70:B3:D5:1D:7/36 (MA-S, Guildford UK); 70:B3:D5:05:5/36 (MA-S, Wayne NJ); 70:B3:D5:02:A/36 (MA-S, Portsmouth UK, BAE Systems Surface Ships Limited); 70:B3:D5:E2:D/36 (MA-S, Guildford UK) [Confirmed] — local IEEE MA-M/MA-S registry mirrors (the IEEE MA-M registry, the IEEE MA-S registry). These are specific sub-allocations under the shared IEEE Registration Authority parent bases 94:05:BB, 8C:1F:64, and 70:B3:D5 (all three registered to "IEEE Registration Authority", 445 Hoes Lane, Piscataway NJ, per the IEEE MA-L registry) — only the seven listed sub-allocations belong to BAE Systems; the bare parent bases must never be claimed as BAE Systems prefixes.

Historic block

none identified [Unknown]

Special note

BAE Systems registers OUIs under multiple corporate entities and addresses (BAE Systems, Inc; BAE Systems Australia (Electronic Systems) Pty Ltd; BAE Systems Surface Ships Limited) rather than one centralized allocation, reflecting its structure as a multinational defense conglomerate. No individual prefix has been tied to a specific product line or device model in this pass. [Confirmed structure; Unknown device mapping] — local IEEE registry mirrors, baesystems.com

Analyst note

multiple registered entities exist under one parent, and no confirmed device-level mapping exists for any prefix — treat a BAE Systems OUI match as "BAE Systems corporate network/equipment," not evidence of a specific product, until a follow-up pass ties a prefix to a named device.
