Palo Alto Networks MAC Addresses
This page provides information about MAC addresses and OUIs assigned to Palo Alto Networks. 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 Palo Alto Networks MAC Addresses
MAC addresses beginning with 00:DA:27: are manufactured by Palo Alto Networks. When you see a device on your network with this OUI prefix, it indicates that the device was manufactured by Palo Alto Networks.
The IEEE assigns OUI prefixes to manufacturers to ensure uniqueness in the global networking ecosystem. Palo Alto Networks has been assigned the OUI prefix 00DA27 (among others) for use in their network devices.
Common Palo Alto Networks Devices
Devices manufactured by Palo Alto Networks 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 Palo Alto Networks Devices on Your Network
To identify Palo Alto Networks 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 Palo Alto Networks devices, the MAC address would look like:
00:DA:27:XX:XX:XX
The first three bytes (00:DA:27) identify the manufacturer as Palo Alto Networks, while the last three bytes are unique to each device.
