MAC vendor lookup
You are encouraged to solve this task according to the task description, using any language you may know.
Every connected device around the world comes with a unique Media Access Control address, or a MAC address. A common task a network administrator may come across is being able to identify a network device's manufacturer when given only a MAC address.
- Basic Task
The task is to interface with one (or numerous) APIs that exist on the internet and retrieve the device manufacturer based on a supplied MAC address.
A MAC address that does not return a valid result should return the String "N/A". A error related to the network connectivity or the API should return a null result.
