ACUCOMM, INC. MAC prefix 00:90:37 — vendor identified, device type unknown
Summary
- // what this is
- Acucomm is registered to MAC prefix
00:90:37in the IEEE OUI database. When a device's MAC address begins with00:90:37, that block was registered by Acucomm — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact prefix match identifies the registry assignment; it does not establish a particular device, deployment, traffic prevalence, or security state. The prefix has 24 suffix bits, or 16,777,216 possible values. Its first-octet Group and Local bits are both zero and fixed for this exact prefix.
About this vendor.
A MAC address beginning 00:90:37 matches an IEEE MA-L assignment to ACUCOMM, INC.; the available records do not identify a device type. The assignment identifies the registered organization for this prefix, but by itself cannot establish which device sent a captured address, whether it is currently deployed, or its security status.
This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical address-space count, not a count of devices or shipments. Under RFC 7042, the first-octet Group bit is bit 0 and the Local bit is bit 1. For 00, both are zero, so they are fixed for an exact 00:90:37 prefix match. Changing either bit produces a different prefix; these bits do not describe variation within this assignment.
The IEEE CSV record gives the company name and a United States country indication. It provides no product, industry, or device-category details. Assignment dates are unavailable in these IEEE CSV records.
