General Electric ("GE") — 2 prefixes (MA-L)
Summary
- // what this is
- General Electric is registered to MAC prefix
DC:37:52and 1 more in the IEEE OUI database. When a device's MAC address begins withDC:37:52, that block was registered by General Electric — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- GE is a substantial, identifiable conglomerate, not a shell registrant — but neither DC:37:52 nor 00:A0:F4 is confirmed to a named device model; treat the grid-relay and healthcare-campus associations as directional context, not device-identification fact.
About this vendor.
A MAC address starting with DC:37:52 or 00:A0:F4 belongs to General Electric, registered under the bare corporate name "GE" rather than one of GE's many product-line divisions — GE Healthcare, GE Lighting, GE Security, GE Vernova, GE Appliances, GE Energy, and others each hold their own, separate OUI assignments and are not part of this entry.
DC:37:52 is registered to an address in Markham, Ontario, Canada that matches GE's Grid Solutions business (formerly GE Digital Energy / GE Multilin), maker of protective relays and substation-automation equipment. This is address corroboration of a plausible product line, not a vendor statement naming a specific model carrying this prefix.
00:A0:F4 is registered to a "W-657" building address on GE's Waukesha, WI campus, the same building-code format documented for a GE Healthcare division entity at a sibling building there. The tie to a specific device or business unit is directional only and unconfirmed.
As of April 2024, General Electric completed a three-way split into GE Aerospace, GE Vernova, and GE HealthCare, each independently traded; GE Aerospace retained the "General Electric Company" name and the ge.com domain. This changes which public company today owns the businesses tied to each address, but not who holds the two OUI records as originally filed.
No CVE or advisory names DC:37:52 or 00:A0:F4 specifically as of an August 2026 search. GE Multilin protective relays (the product family tied to the Markham address) and GE HealthCare Vivid-series ultrasound systems (a product family that could plausibly trace to the Waukesha campus) each carry documented CISA/CVE history, but none of those advisories are tied to hardware confirmed to carry these exact prefixes.
- IEEE assignment
- DC3752 → "GE", 650 Markland Street, Markham, Ontario, CA L6C 0M1; 00A0F4 → "GE", W-657, Waukesha, WI, US 53188 [Confirmed] — the IEEE MA-L registry DC3752, the IEEE MA-L registry 00A0F4
- Registry / block size
- MA-L (24-bit OUI); this entry covers exactly 2 IEEE prefixes registered under the bare literal name "GE" [Confirmed] — the IEEE MA-L registry
- HQ / country
- two distinct registrant addresses — Markham, Ontario, CA (DC3752) and Waukesha, WI, US (00A0F4); no single HQ address applies to both [Confirmed] — the IEEE MA-L registry
- Company status
- active — General Electric completed a three-way corporate split into GE Aerospace, GE Vernova, and GE HealthCare effective 2 April 2024; GE Aerospace retained the General Electric Company name [Confirmed] — cnbc.com (2024-04-02), ge.com/investor-relations/spinoff-resources
- Device types
- DC3752 → grid protection relays / substation automation equipment (GE Grid Solutions/Multilin business at the same address) [Likely] — maclookup.app/macaddress/dc3752; 00A0F4 → possible GE Healthcare-adjacent equipment on the same Waukesha campus [Unknown] — maclookup.app/macaddress/00a0f4
- Notable products
- none independently confirmed for either prefix [Unknown]
- Verified sample prefixes (both MA-L, registrant "GE")
- DC:37:52, 00:A0:F4 [Confirmed] — the IEEE MA-L registry
- Related but out-of-scope GE-division registrations (separate registrant rows, NOT part of this entry)
- 44:4B:5D (GE Healthcare), 00:17:55 (GE Security), DC:2F:FA / 34:13:43 / 78:6D:EB (GE Lighting — has its own vendor-ge-lighting entry), 50:E0:F9 (GE Vernova), FC:B9:7E / CC:EA:27 (GE Appliances), 00:D6:32 (GE Energy), A0:F2:17 (GE Medical System(China)), 00:1F:44 (GE Transportation Systems), 00:30:2F (GE Aviation System)[Confirmed] — the IEEE MA-L registry
- Third-party date caveat
- maclookup.app displays "Date Registered: 01 March 2016" for DC3752 and "Initial registration: 22 April 1998 / Most recent update: 17 November 2015" for 00A0F4; these are third-party database-scrape artifacts, not IEEE-published facts — IEEE's own OUI registry publishes no registration-date field[Confirmed] — maclookup.app/macaddress/dc3752, maclookup.app/macaddress/00a0f4
- Security context
- no CVE or advisory names DC3752 or 00A0F4 specifically as of an August 2026 search; documented CISA/CVE history exists for the plausibly-related GE Multilin protective-relay line (CVE-2017-7905, ICSA-17-117-01B) and the GE HealthCare Vivid ultrasound line (2024 multi-CVE disclosure), but neither is tied to hardware confirmed to carry these exact prefixes [Confirmed for absence of a direct match; Likely as general product-family context] — cisa.gov/news-events/ics-advisories/icsa-17-117-01b, cisa.gov/news-events/ics-medical-advisories/icsma-20-049-02
- Analyst note
- General Electric is a substantial, identifiable company holding well over a dozen independent OUI assignments across its divisions; the two bare-"GE" rows each have address corroboration to a real GE facility, but neither is confirmed to a named device model — treat device-type claims here as directional, not definitive [Likely]
