MAC Vendor Lookup

Hey guys, I've made an app to search for a network card manufacturer by it's MAC address.

To those who doesn't know, (I might be wrong but in general -) every network card has a unique identifier called a MAC address, it's 6 bytes in hexadecimal format separated by - or :, the first 3 bytes identify the manufacturer of the card and the last 3 are just so every card by this manufacturer will be unique.

Anyhow, the app, has a text input field, you can input whatever you want, it will search for the first 3 hexadecimal bytes separated by the separators below and will search a constant key,value database for the value of this key if it exists, the value will be the vendor.

I made it for a project I needed (there are similar apps or tools online but some where outdated so I decided to implement one of my own) if you will find it useful, this is the application, if someone will need the code, I'll gladly share it.
