```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

```

```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'
