Summary
- // what this is
- Aastra Telecom is registered to MAC prefix
00:10:BCin the IEEE OUI database. When a device's MAC address begins with00:10:BC, that block was registered by Aastra Telecom — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The first 24 bits match this assignment; the remaining 24 bits permit 16,777,216 possible suffix values, not an observed device or shipment count. The Group and Local bits in the first octet 00 are both zero and are fixed for this exact prefix. A matching address identifies the registry assignment only.

About this vendor.
Updated · Confidence: High · 2 sources · How this page is checked
A MAC address beginning 00:10:BC matches an IEEE MA-L assignment registered to Aastra Telecom. The supplied record does not identify a device type, product, or deployment using this prefix.
The assignment covers the first 24 bits of a 48-bit MAC address. The remaining 24 bits allow 16,777,216 possible suffix values; that is a count of possible values, not devices or shipments. For this exact prefix, the first octet is 00: its Group bit and Local bit are both zero. Those bits are fixed for a literal 00:10:BC match. Changing either bit changes the prefix.
A captured match supports identifying the registered assignment only. It cannot establish a particular device, current vendor identity, traffic prevalence, or security status.
