Note that the oui.txt file seperates the MAC address by dashes rather than colons. MACAddressView is a MAC address lookup tool that allows you to easily find the company details (company name, address, and country) according to the MAC. If you're wanting to look up a larger amount or a list of MAC addresses it will be easier to run a script to grab the line (using grep or something similar) from IEEE's OUI List. When online I use MAC_Find: - it's helpful if you're only looking up one or two.
