Ventilation Control MAC Addresses
This page provides information about MAC addresses and OUIs assigned to Ventilation Control. 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 Ventilation Control MAC Addresses
MAC addresses beginning with 80:4B:20: are manufactured by Ventilation Control. When you see a device on your network with this OUI prefix, it indicates that the device was manufactured by Ventilation Control.
The IEEE assigns OUI prefixes to manufacturers to ensure uniqueness in the global networking ecosystem. Ventilation Control has been assigned the OUI prefix 804B20 (among others) for use in their network devices.
Common Ventilation Control Devices
Devices manufactured by Ventilation Control 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 Ventilation Control Devices on Your Network
To identify Ventilation Control 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 Ventilation Control devices, the MAC address would look like:
80:4B:20:XX:XX:XX
The first three bytes (80:4B:20) identify the manufacturer as Ventilation Control, while the last three bytes are unique to each device.
