```javascript
const net = require('extra-net');
var {family, address} = net.address();
// family: 'IPv4', address: '192.168.1.7'
var port = await net.freePort();
// port: 37567
```
## reference
```javascript
const net = require('extra-net');
// : includes all functions of "net"
net.address([options]);
options = {
internal: Boolean, // true | false (default)
address: String, // 'IPv4' | 'IPv6'
netmask: String, // e.g., '255.255.255.0'
}
-> {address, netmask, family, mac, internal, cidr}
net.freePort([host]);
host = String // e.g., '127.0.0.1'
-> Promise port
