OTRUM ASA MAC Addresses
This page provides information about MAC addresses and OUIs assigned to OTRUM ASA. 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 OTRUM ASA MAC Addresses
MAC addresses beginning with 00:0A:EF: are manufactured by OTRUM ASA. When you see a device on your network with this OUI prefix, it indicates that the device was manufactured by OTRUM ASA.
The IEEE assigns OUI prefixes to manufacturers to ensure uniqueness in the global networking ecosystem. OTRUM ASA has been assigned the OUI prefix 000AEF (among others) for use in their network devices.
Common OTRUM ASA Devices
Devices manufactured by OTRUM ASA 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 OTRUM ASA Devices on Your Network
To identify OTRUM ASA 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 OTRUM ASA devices, the MAC address would look like:
00:0A:EF:XX:XX:XX
The first three bytes (00:0A:EF) identify the manufacturer as OTRUM ASA, while the last three bytes are unique to each device.
