Revision history [back]

The Go Deep website oui-lookup tool searches only the descriptive text to the right of the MAC address, but no longer lets one search the MAC address itself. Enter '00:00' and it will not even find a single XEROX entry even though when you search for XEROX, those show up as the first ten entries. Type in '24', it will not find ubiquiti even though some of their MAC addresses start with 24. Notice, it is only returning text containing '24'.

I often find myself on a machine that WireShark cannot be installed on - dedicated network hardware or my smartphone. But want to check possible vendors for a random MAC address on whatever network I am managing.
For a decade or so, i went to the wireshark oui lookup tool.
