Thank you for contacting Intel Embedded Community.
In order to be on the same page, could you please clarify if the affected design has been developed by you or a third-party company? In case that it is a third-party device, could you please let us know all the information related to it?
Waiting for reply for the information that should answer these questions.
Thank you for your apply. The affected design has been developed by our company.I use I211-AT for internet development，but I don't have valid MAC address。I don't know who to apply for a MAC address， Intel or other organization？In case for Intel ,how can I apply?
Thanks for your reply.
We suggest you as a reference to review the information stated at the following website:
By the way, in case that you want to write the Intel(R) Ethernet Controller I211-AT MAC address please use the Intel(R) LANConf Software Tool, which is included in the https://cdrdv2.intel.com/v1/dl/getContent/348742 Intel(R) Network Connections Tools 23.4 PV LAN Software Tools document # 348742.
It is accessible when you are logged into your Resource and Design Center (RDC) privileged account.
This account can be requested by filling out the https://www.intel.com/content/www/us/en/forms/design/contact-support.html RDC Account Support form.
We hope that this information may help you.
You need to apply to the IEEE.
https://standards.ieee.org/faqs/regauth.html# 2 IEEE-SA - IEEE Registration Authority
You fill in the form and pay for the MAC addresses you need and they will send you a block of addresses.
