7C:1E:B3 identifies a registry assignment to 2N TELEKOMUNIKACE a.s.; device type unknown
Summary
- // what this is
- 2N Telekomunikace is registered to MAC prefix
7C:1E:B3in the IEEE OUI database. When a device's MAC address begins with7C:1E:B3, that block was registered by 2N Telekomunikace — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A captured address matching 7C:1E:B3 establishes an exact 24-bit prefix match. The first-byte Group and Local bits are both zero and fixed for this literal prefix; changing either bit yields a different prefix. The remaining 24 bits permit 16,777,216 suffix values, not a device or shipment count. A prefix match identifies a registry assignment and does not identify a specific device, product, current operator, or security state.
About this vendor.
A MAC address beginning 7C:1E:B3 matches an IEEE MA-L assignment to 2N TELEKOMUNIKACE a.s. The prefix identifies a registry allocation; available evidence does not identify a device category or show that a particular product uses it.
This is a 24-bit prefix, so an exact match requires the first three address octets to be 7C:1E:B3. The first octet, 7C, has Group and Local bits both zero. Those bits are fixed for this literal prefix; changing either produces a different prefix. The remaining 24 bits allow 16,777,216 possible suffix values, not a count of devices or shipments.
The company’s purchasing terms identify its legal name and state that it is based in Prague, Czech Republic. They refer generally to products purchased by the company, without naming a product catalog or linking products to this prefix. A prefix match alone cannot establish which device sent an address, its current operator, or its security state.
