Samsung Electronics Co., Ltd., Memory Division: Registered MA-L vendor; device identity unknown
Summary
- // what this is
- Samsung Electronics Co., Ltd., Memory Division is registered to MAC prefix
00:25:38and 1 more in the IEEE OUI database. When a device's MAC address begins with00:25:38, that block was registered by Samsung Electronics Co., Ltd., Memory Division — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A prefix match identifies a registry assignment only. For each exact 24-bit prefix, the first-byte Group and Local bits are zero; each leaves 24 suffix bits, allowing 16,777,216 possible suffix values, not evidence of an actual device or shipment count.
About this vendor.
A MAC address beginning with 00:25:38 or 18:BF:B3 matches an IEEE MA-L assignment to Samsung Electronics Co., Ltd., Memory Division; the assignment alone does not identify a device or establish that the vendor currently made it. The IEEE records give country-level address information indicating South Korea, but do not provide assignment dates.
Both prefixes are 24 bits long, leaving 24 bits for suffix values. Each therefore has 16,777,216 mathematically possible suffix values; this is not a count of devices, shipments, or observed addresses. The first-byte Group and Local bits are both zero for these exact prefixes. A captured address matching one of them supports a prefix match only, not a product, operating system, deployment, or security conclusion.
