MAC address vendor

Actlas Inc. MAC Prefix 44:EA:4B — Vendor Identified; Device Unknown

Primary prefix
44:EA:4B
Block
MA-L

Summary

// what this is
Actlas is registered to MAC prefix 44:EA:4B in the IEEE OUI database. When a device's MAC address begins with 44:EA:4B, that block was registered by Actlas — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A match to this 24-bit prefix identifies the IEEE registry assignment. The remaining 24 bits allow 16,777,216 possible suffix values, not an observed device or shipment count. The Group and Local bits in first octet 44 are both zero; changing either bit changes the prefix.

About this vendor.

Updated  ·  Confidence: High  ·  4 sources  ·  How this page is checked

A MAC address beginning with 44:EA:4B matches an IEEE MA-L assignment to Actlas Inc.; the available evidence does not identify a device category or product using it. A match identifies the registry assignment associated with the prefix, not the device, operating system, current legal identity, or security state of a captured address.

The prefix is 24 bits long, leaving 24 bits in a 48-bit MAC address. That allows 16,777,216 possible suffix values under the prefix; this is a mathematical range, not a count of devices or shipments. For this exact prefix, the first octet is 44 hexadecimal: its Group bit and Local bit are both zero. Changing either bit changes the prefix and is not a variation within this fixed assignment.

RFC 7042 describes MAC identifiers as using an assigned initial prefix followed by remaining bits, and explains the Group and Local bits. IEEE CSV records list one MA-L assignment for Actlas Inc. and no assignments for this company in the supplied MA-M or MA-S records. Assignment dates are unavailable in these IEEE CSV records.

Device class
Unknown; no device category is mapped to this exact prefix in the supplied evidence.
Matching prefix
44:EA:4B (24 bits, MA-L).
Address range
24 suffix bits allow 16,777,216 possible values; this is not an observed device count.
Group and Local bits
Both are zero in first octet 44; changing either bit changes the prefix.
