|
> 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).
|
||
|
|
||
|
## Installation
|
||
|
|
||
|
```
|
||
|
$ npm install default-gateway
|
||
|
```
|
||
|
|
||
|
## Example
|
||
|
|
||
|
```js
|
||
|
const defaultGateway = require('default-gateway');
|
||
|
|
||
|
defaultGateway.v4().then(result => {
|
||
|
// result = {gateway: '1.2.3.4', interface: 'en1'}
|
||
|
});
|
||
|
|
||
|
defaultGateway.v6().then(result => {
|
||
|
// result = {gateway: '2001:db8::1', interface: 'en2'}
|
||
|
});
|
||
|
|
||
|
const result = defaultGateway.v4.sync();
|
||
|
// result = {gateway: '1.2.3.4', interface: 'en1'}
|
||
|
|
||
|
const result = defaultGateway.v6.sync();
|
||
|
// result = {gateway: '2001:db8::1', interface: 'en2'}
|
||
|
```
|
||
|
|
||
|
## 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.
