Josh-

The first half of an IEEE 802-series standard MAC address is the
Organizationally Unique Identifier.

Look them up or download the latest copy here:
http://standards.ieee.org/regauth/oui/index.shtml

For an OUI FAQ, see http://standards.ieee.org/faqs/OUI.html

A lot of software uses this information, or this combined with other
supplemental information when telling you what manufacturer claims the MAC
address you see on your network (Ethereal, many others).
