  - hostname
```
public static String hostname()

    Returns:
    
    a string
  - mac
```
public static String mac(NetworkInterface nic)
```
    Returns the MAC address if found. Output format: "00-00-00-00-00-00" (in upper case)
    
    Returns:
    
    a string

  - nic
```
public static NetworkInterface nic()
```
    Returns a network interface. It tries to return the network interface associated to the host name. If that network interface is not found, it tries to return the first network interface that satisfies these conditions: - it is up and running; - it is not loopback; - it is not virtual; - it has a hardware address. If no acceptable network interface is found, it returns null.
    
    Returns:
