Returns: result Object

• gateway: The IP address of the default gateway.
• interface: The name of the interface. On Windows, this is the network adapter name.

The .v{4,6}() methods return a Promise while the .v{4,6}().sync() variants will return the result synchronously.

The gateway property will always be defined on success, while interface can be null if it cannot be determined. All methods reject/throw when the gateway cannot be determined or the exec call failed.
