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()

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.
