Get current machine IP, MAC and DNS servers.
|
||
|
|
|
||
|
|
DNS servers receive from `/etc/resolv.conf`.
|
||
|
|
|
||
|
|
## Install
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ npm install address
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Get IP is sync and get MAC is async for now.
|
||
|
|
|
||
|
|
```js
|
||
|
|
var address = require('address');
|
||
|
|
|
||
|
|
// default interface 'eth' on linux, 'en' on osx.
|
||
|
|
address.ip(); // '192.168.0.2'
|
||
|
|
address.ipv6(); // 'fe80::7aca:39ff:feb0:e67d'
|
||
|
|
address.mac(function (err, addr) {
|
||
|
|
console.log(addr); // '78:ca:39:b0:e6:7d'
|
||
|
|
});
|
||
|
|
|
||
|
|
// local loopback
|
||
|
|
address.ip('lo'); // '127.0.0.1'
|
||
|
|
|
||
|
|
// vboxnet MAC
|
||
|
|
address.mac('vboxnet', function (err, addr) {
|
||
|
|
console.log(addr); // '0a:00:27:00:00:00'
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
### Get all addresses: IPv4, IPv6 and MAC

||
|
|
|
||
|
|
```js
|
||
|
|
address(function (err, addrs) {
|
||
|
|
console.log(addrs.ip, addrs.ipv6, addrs.mac);
|
||
|
|
// '192.168.0.2', 'fe80::7aca:39ff:feb0:e67d', '78:ca:39:b0:e6:7d'
|
||
|
|
});
|
||
|
|
|
||
|
|
address('vboxnet', function (err, addrs) {
|
||
|
|
console.log(addrs.ip, addrs.ipv6, addrs.mac);
|
||
|
|
// '192.168.56.1', null, '0a:00:27:00:00:00'
|
||
|
|
});
|
||
|
|
```

|
address.interface('IPv4', 'eth1');
|
||
|
|
// { address: '192.168.1.1', family: 'IPv4', mac: '78:ca:39:b0:e6:7d' }
|
||
|
|
```
|
||
|
|
|
||
|
|
### Get DNS servers

console.log(addrs);
|
||
|
|
// ['10.13.2.1', '10.13.2.6']
