### Environment

* Dubbo version: master
* Operating System version: all platform
* Java version: all version

### Steps to reproduce this issue

1. set SystemProperty "java.net.preferIPv6Addresses" to true.
2. call org.apache.dubbo.common.utils.NetUtils#isPreferIPV6Address().
3. check the return value.

### Expected Result

org.apache.dubbo.common.utils.NetUtils#isPreferIPV6Address() will return true when SystemProperty "java.net.preferIPv6Addresses" set to true.

### Actual Result

org.apache.dubbo.common.utils.NetUtils#isPreferIPV6Address() method ignore SystemProperty "java.net.preferIPv6Addresses" and always return false
