ACCESS Systems Americas, Inc. — MAC prefix identification
Summary
- // what this is
- ACCESS Systems Americas is registered to MAC prefix
00:0E:20in the IEEE OUI database. When a device's MAC address begins with00:0E:20, that block was registered by ACCESS Systems Americas — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- For exact prefix
00:0E:20, the first-byte Group and Local bits are both zero and fixed. This 24-bit assignment leaves 24 suffix bits, or 16,777,216 possible suffix values; this is not a device or shipment count. A matching captured address supports only registry attribution, not device identity, deployment, current legal identity, or security state.
About this vendor.
A MAC address beginning 00:0E:20 matches an IEEE MA-L assignment to ACCESS Systems Americas, Inc.; the record does not identify a device category or product using that prefix. The assignment establishes the registry match only, not who deployed an address or whether it is in use.
This is one 24-bit prefix, leaving 24 suffix bits and 16,777,216 possible suffix values. That is a mathematical address space, not a count of devices or shipments. The first byte is 00: the Group bit and Local bit are both zero. For this exact prefix, those bits are fixed; toggling either changes the prefix and no longer matches this assignment.
RFC 7042 describes 48-bit MAC identifiers as an assigned initial prefix followed by additional bits, and explains the significance of the Group and Local bits. A captured address matching this prefix can support a registry attribution to the named assignee, but cannot establish a particular device, operating system, current corporate identity, or security state. The supplied IEEE CSV record includes no assignment date.
