Cathexis MAC Addresses

Primary OUI: 00:19:D0:
Total OUIs: 2
Last Updated: July 3, 2026

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

MAC addresses beginning with 00:19:D0: are manufactured by Cathexis. When you see a device on your network with this OUI prefix, it indicates that the device was manufactured by Cathexis.

The IEEE assigns OUI prefixes to manufacturers to ensure uniqueness in the global networking ecosystem. Cathexis has been assigned the OUI prefix 0019D0 (among others) for use in their network devices.

Common Cathexis Devices

Devices manufactured by Cathexis 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 Cathexis Devices on Your Network

To identify Cathexis 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 Cathexis devices, the MAC address would look like:

00:19:D0:XX:XX:XX

The first three bytes (00:19:D0) identify the manufacturer as Cathexis, while the last three bytes are unique to each device.
