How to get InetAddress with wildcard ip 0.0.0.0?

Question

`InetAddress` doesn't provide any static method or constructor to get `InetAddress` with wildcard IP 0.0.0.0 . The only way is `InetAddress.getByName("0.0.0.0")` But PMD gives `AvoidUsingHardCodedIP` if we pass hard coded IP. Is there any way to get `InetAddress` with wildcard IP but without hard coding the IP?

Accepted Answer

I know that this is a little bit old. But i was in the same situation:

```
InetAddress wildCard = new InetSocketAddress(0).getAddress();
```

does the trick. The main constructor

```
public InetSocketAddress(InetAddress addr, int port)
```

will be called with

```
InetAddress.anyLocalAddress() 
```

The port is not needed so i picked 0.
