We are happy to announce that Onion Corporation has a new MAC address block. Onion devices can now have MAC addresses in the range of 88:1E:59:00:00:00 – 88:1E:59:FF:FF:FF, with 88:1E:59 being the new OUI (Organizationally Unique Identifier).

What is a MAC Address?

A MAC address, or Media Access Control address, is a unique identifier assigned to network interfaces for communications within a network network segment. Every Omega2 device is allocated three sequential MAC address during production, one for each of the available network interfaces:

  • The WiFi Access Point interface
  • The Ethernet port
  • The WiFi client interface

Why Do We Need a New Range?

Simply because we’ve used every single available MAC address in our existing 40:A3:6B:C OUI. This is cause for celebration since that means there’s been a whole medium block worth of Omega devices manufactured and shipped!

When will Devices with the New Range Ship?

We’ve produced Omega2 devices with the new MAC address range in our latest manufacturing run in November 2022. These devices will start shipping to customers shortly. Distributors may still have inventory with the previous MAC address range, so you may receive devices with the previous and the new range for the next little while.

Going forward, we will only be manufacturing devices using the new MAC address range.

How does this affect me, an Omega2 user?

There is no action required on your end. Omega2 devices with MAC addresses in the new 88:1E:59 OUI will behave the same as those with the 40:A3:6B:C OUI. The MAC address acts as a unique identifier but does not change any device functionality. 

We are excited about this new MAC address range and we know our customers will be too. We look forward to continuing to ship IoT devices to our customers, and eventually using up all the MAC addresses in this new block too. Here’s to the future!
