dhcp-lease-list on my Ubuntu router to pull up the list assigned IPs it has given out on my network.
There is a manufacturer column in the output that is empty.
Above the whole table, there’s a message:
“To get manufacturer names please download http://standards.ieee.org/regauth/oui/oui.txt to /usr/local/etc/oui.txt”
The problem is, that URL doesn’t work.
In my research, I saw that the URL for that file has moved and this isn’t the first time either.
The current URL that works is https://standards-oui.ieee.org/oui/oui.txt.
Download this file to
/usr/local/etc/out.txt and then run
dhcp-lease-list again and you’ll be golden.
Here’s a quick one-liner you can copy and paste:
sudo wget -O /usr/local/etc/oui.txt "https://standards-oui.ieee.org/oui/oui.txt"
