14:24:75 — IEEE assignment to 4DReplay, Inc
Summary
- // what this is
- 4DReplay is registered to MAC prefix
14:24:75in the IEEE OUI database. When a device's MAC address begins with14:24:75, that block was registered by 4DReplay — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- For
14:24:75, the Group and Local bits in the first octet are both zero. The exact prefix boundary is 24 bits, leaving 24 suffix bits (16,777,216 possible values), not an observed device or shipment count.
About this vendor.
A MAC address beginning 14:24:75 matches the IEEE MA-L assignment registered to 4DReplay, Inc. This identifies the registry record for the prefix; by itself, it does not identify a particular device, product, operating system, current company identity, or security state.
The assignment is 24 bits long, leaving 24 bits in a 48-bit MAC address. The first octet is 14 hexadecimal: its Group bit and Local bit are both zero. For an exact 14:24:75 prefix match, those bits are fixed; changing either bit produces a different prefix. RFC 7042 describes these bits’ significance in MAC addresses.
There are 16,777,216 possible values for the remaining 24 bits. That is the size of the suffix space, not a count of observed devices, active addresses, or shipments. The supplied IEEE CSV records display no assignment date.
- Registry match
14:24:75is assigned under MA-L to 4DReplay, Inc.- Address boundary
- The match covers the first 24 bits of a 48-bit MAC address; 24 suffix bits remain.
- Interpretation
- Group and Local bits are both zero for this exact prefix. A prefix match establishes the registry assignment, not a specific device or product.
