PRECIA MAC Addresses

Primary OUI: 10:CA:81:
Total OUIs: 2
Last Updated: July 3, 2026

This page provides information about MAC addresses and OUIs assigned to PRECIA. 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 PRECIA MAC Addresses

MAC addresses beginning with 10:CA:81: are manufactured by PRECIA. When you see a device on your network with this OUI prefix, it indicates that the device was manufactured by PRECIA.

The IEEE assigns OUI prefixes to manufacturers to ensure uniqueness in the global networking ecosystem. PRECIA has been assigned the OUI prefix 10CA81 (among others) for use in their network devices.

Common PRECIA Devices

Devices manufactured by PRECIA 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 PRECIA Devices on Your Network

To identify PRECIA devices on your network:

  1. Use network scanning tools to list devices on your network
  2. Look for MAC addresses starting with any of the OUI prefixes listed in the sidebar
  3. 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 PRECIA devices, the MAC address would look like:

10:CA:81:XX:XX:XX

The first three bytes (10:CA:81) identify the manufacturer as PRECIA, while the last three bytes are unique to each device.
