EM-Tech MAC Addresses
This page provides information about MAC addresses and OUIs assigned to EM-Tech. The Organizationally Unique Identifier (OUI) is the first 24 bits of a MAC address and is assigned by the IEEE to uniquely identify a vendor or manufacturer.
About EM-Tech MAC Addresses
MAC addresses beginning with BC:B2:2B: are manufactured by EM-Tech. When you see a device on your network with this OUI prefix, it indicates that the device was manufactured by EM-Tech.
The IEEE assigns OUI prefixes to manufacturers to ensure uniqueness in the global networking ecosystem. EM-Tech has been assigned the OUI prefix BCB22B (among others) for use in their network devices.
Common EM-Tech Devices
Devices manufactured by EM-Tech that you might encounter on networks include:
- Network interface cards (NICs)
- Routers and switches
- Wireless access points
- IoT devices
- Embedded systems
- And other networking equipment
Identifying EM-Tech Devices on Your Network
To identify EM-Tech devices on your network:
- Use network scanning tools to list devices on your network
- Look for MAC addresses starting with any of the OUI prefixes listed in the sidebar
- Use our MAC address lookup tool to confirm the manufacturer
This can be particularly helpful for network inventory, troubleshooting, and security auditing.
MAC Address Format
A complete MAC address consists of 48 bits (6 bytes) and is typically represented in hexadecimal format with each byte separated by a colon or a hyphen. For EM-Tech devices, the MAC address would look like:
BC:B2:2B:XX:XX:XX
The first three bytes (BC:B2:2B) identify the manufacturer as EM-Tech, while the last three bytes are unique to each device.
