method Server.prototype.address
Usage in Deno
```typescript import { Server } from "node:node__net.d.ts"; ```
Server.prototype.address():
Returns the bound `address`, the address `family` name, and `port` of the server
as reported by the operating system if listening on an IP socket
(useful to find which port was assigned when getting an OS-assigned address):`{ port: 12346, family: 'IPv4', address: '127.0.0.1' }`.
For a server listening on a pipe or Unix domain socket, the name is returned
as a string.
```js
const server = net.createServer((socket) => {
socket.end('goodbye\n');
}).on('error', (err) => {
// Handle errors here.
throw err;
});
// Grab an arbitrary unused port.
server.listen(() => {
console.log('opened server on', server.address());
});
```
`server.address()` returns `null` before the `'listening'` event has been
emitted or after calling `server.close()`.
