Populate Manufacturers for 'isc-dhcp-server' Leases

Posted on

I ran 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"
