+# default-gateway
+[![](https://img.shields.io/npm/v/default-gateway.svg?style=flat)](https://www.npmjs.org/package/default-gateway) [![](https://img.shields.io/npm/dm/default-gateway.svg)](https://www.npmjs.org/package/default-gateway)
+
+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 Windows, `wmic` must be available.
+- On IBM i, the `db2util` command must be available (provided by the `db2util` package).
+- On Unix (and macOS), the `netstat` command must be available.
+
+## Installation
+
+```
+$ npm i default-gateway
+```
+
+## Example
+
+```js
+const defaultGateway = require('default-gateway');
+
+const {gateway, interface} = await defaultGateway.v4();
+// gateway = '1.2.3.4', interface = 'en1'
+
+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();
+// 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.
