macdb

A sane way to access MAC addresses in the IEEE MA-L/OUI public listing.

The IEEE MA-L/OUI listing used to be a horrid mess of mixed whitespace characters and duplicate information. macdb attempted to correct those errors by recreating the listing in common, parsable formats.

Update:

The IEEE now provides a much easier way to view the assignments. I recommend visiting their updated registry. If you're still interested in the original listing you can find something like it here.
