ADSOFT, LTD. — MAC prefix identifies a registry assignment
Summary
- // what this is
- Adsoft is registered to MAC prefix
00:80:57in the IEEE OUI database. When a device's MAC address begins with00:80:57, that block was registered by Adsoft — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A match on 00:80:57 establishes the assigned MA-L prefix only; it does not establish deployment, product, traffic prevalence, or security state.
About this vendor.
A MAC address beginning 00:80:57 matches the IEEE MA-L assignment registered to ADSOFT, LTD.; the record does not identify a specific device or product. The assignment date is not shown in the supplied IEEE CSV record.
This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is an address-space size, not a count of devices, shipments, or observed traffic. A matching address supports the prefix match only; it does not establish who deployed the interface or its security state.
The first byte 00 has Group bit 0 and Local bit 0. Those bits are fixed for this exact literal prefix. Changing either bit changes the prefix, so variations sharing other bits are not exact matches to 00:80:57. RFC 7042 describes MAC identifiers as an assigned initial prefix followed by remaining bits; matching at this boundary does not identify a particular interface.
