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).
$ npm install default-gateway
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'}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 when the gateway cannot be determined or the exec call failed.
