## Example
|

||
|
|
|

|
||
|
|
|
||
|
|
const {gateway, interface} = await defaultGateway.v6();
|
||
|
|
// gateway = '2001:db8::1', interface = 'en2'
|
||
|
|
|
||
|
|
const {gateway, interface} = defaultGateway.v4.sync();
|
||
|
|
// gateway = '1.2.3.4', interface = 'en1'
|
||
|
|
|
||
|
|
const {gateway, interface} = defaultGateway.v6.sync();
|
||
|

## API
|
||
|
|
### defaultGateway.v4()
|
||
|
|
### defaultGateway.v6()
|
||
|
|
### defaultGateway.v4.sync()
|
||
|
|
### defaultGateway.v6.sync()
|
||
|
|
|
||
|
|
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 on unexpected conditions.
