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?

@NikolayKuznetsov one of the method I am calling accepts InetAddress as an argument. Where I passed InetAddress.getByName("0.0.0.0") but PMD is showing AvoidUsingHardCodedIP error. — anupsth, Dec 04 '12 at 08:15

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.

use InetAddress.getByAddress(new byte[] {0,0,0,0}) will work. but don't forget to check listen on ipv4 or ipv6.
