Get your internal IP address

Install

$ npm install internal-ip

Usage

const internalIp = require('internal-ip');

(async () => { console.log(await internalIp.v6()); //=> 'fe80::1'

console.log(await internalIp.v4());
//=> '10.0.0.79'

})();

console.log(internalIp.v6.sync()) //=> 'fe80::1'

console.log(internalIp.v4.sync()) //=> '10.0.0.79'

The module returns the address of the internet-facing interface, as determined from the default gateway. When the address cannot be determined for any reason,

undefined
will be returned.

The module relies on operating systems tools. On Linux and Android, the

ip
command must be available, which depending on distribution might not be installed by default. It is usually provided by the
iproute2
package.
