Examples

# Using colon separator
$ maclookup 74:4d:28:ab:ba:ab
74:4d:28:ab:ba:ab Routerboard.com

# Using hyphen separator
$ maclookup 74-4d-28-ab-ba-ab

How it Works

1. The tool first checks if the OUI database is cached locally
2. If not found, it downloads the latest OUI database from IEEE
3. The MAC address is normalized and the vendor is looked up
4. The result is displayed in a simple format
