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

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.
