Improved on one of the SG network tools today, added some ajax functionality, updated the database with the latest OUI data, etc. It is a MAC Address OUI lookup tool, that can be used to find your network adapter/IoT device manufacturer by pasting its MAC address into a form. It can be useful in identifying IoT devices on your network, network adapter manufacturers, etc. It has been updated with the latest IEEE data from this month.

I sometimes have to lookup network device manufacturers, I hope others find it useful as well.
