Murrelektronik GmbH — MAC prefix identification
Summary
- // what this is
- Murrelektronik is registered to MAC prefix
4C:EB:76and 1 more in the IEEE OUI database. When a device's MAC address begins with4C:EB:76, that block was registered by Murrelektronik — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
About this vendor.
A MAC address beginning with 4C:EB:76 or 00:0F:9E matches an IEEE MA-L assignment to Murrelektronik GmbH. That identifies the registry name associated with the prefix; it does not establish the device maker, a specific product, or the current operator of a captured address.
Both assignments are 24-bit prefixes. Under RFC 7042, the first octet’s Group bit is bit 0 and Local bit is bit 1; both are zero in these exact prefixes (4C and 00). The matching boundary is the first 24 bits, leaving 24 suffix bits, or 16,777,216 possible values per prefix. That is a range of possible identifiers, not a count of devices or shipments. Changing either first-octet bit changes the prefix and no longer matches this exact assignment.
Murrelektronik GmbH’s supplied impressum identifies Germany and lists a company registration with Amtsgericht Stuttgart. The available evidence does not map either prefix to a product or device category.
