Getting the vendor from an ethernet network MAC address on-line through the Wireshark OUI Lookup Tool.

Posted by jpluimers on 2016/11/18

In networks, often you want to know which manufacturer or vendor is behind a MAC address.

An easy way to look this up on-line is by using the
Wireshark · OUI Lookup Tool which should have had MAC or MAC address in the title.

It uses both the extensive /etc/manuf Wireshark Ethernet vendor codes and well-known MAC address prefixes (which is a long text file generated from several sources). Some of the prefixes are just the 24-bit (6-hex digit) OUIs, but others are much more fine grained.

What’s really cool is that the tool accepts a very lenient formatting of inputs: full, partial, various hex separators (including none), case insensitive, and vendor names/abbreviations. So entries like these magically work.
