There are whole sites dedicated to looking up MAC address ( ). It would be great if I can type in either the whole MAC Address or just the prefix (first 3 hex octets) and have an instant answer pop up with the Vendor ID or OUI ( )

I often lookup the MAC Address of people connecting to my WiFi to see what devices they are using. This would be an invaluable tool for Network Administrators.

Sometimes the search is right on, and other times it is buried so far down it is difficult to find.

For example, searching for DuckDuckGo for "DC:2B:61" (even in quotes), the answer I want is way far down the list.

It would be nice if the first answer was "DC:2B:61:00:00:00 - DC:2B:61:FF:FF:FF MAC Address of Apple, Inc (Apple)" or something along those lines.

The lookup data table can be found at:
