> Get the default network gateway, cross-platform.

Obtains the machine's default gateway through `exec` calls to OS routing interfaces. On Linux and Android, the `ip` command must be available (usually provided by the `iproute2` package). On IBM i, the `db2util` command must be available (provided by the `db2util` package).

- On Unix (and macOS), the `netstat` command must be available.

const defaultGateway = require('default-gateway');

  // result = {gateway: '1.2.3.4', interface: 'en1'}

const {gateway, interface} = await defaultGateway.v4();

// gateway = '1.2.3.4', interface = 'en1'

  // result = {gateway: '2001:db8::1', interface: 'en2'}

const {gateway, interface} = await defaultGateway.v6();

// gateway = '2001:db8::1', interface = 'en2'

// result = {gateway: '1.2.3.4', interface: 'en1'}

const {gateway, interface} = defaultGateway.v4.sync();

// result = {gateway: '2001:db8::1', interface: 'en2'}

const {gateway, interface} = defaultGateway.v6.sync();

  - `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 on unexpected conditions.
