I have a list of MAC addresses coming from a database. I would like to lookup the vendor for each MAC address and then have a count of devices on network by vendor in the end.
I believe I could do it the dirty way which would be to parse the vendor prefixes from the file available here http://standards.ieee.org/develop/regauth/oui/oui.txt.
But I’m wondering if there is a better way ?
There is a library in Pear, but it does have substantial overhead involved in that the vendor lookup requires a relational database that’s been loaded with the vendor data. However, considering the alternative this might be worth exploring.

The package provides a loader for the list maintained by wireshark: https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blob_plain;f=manuf
