```
public class HostInterface
extends Object
```
Utility class for network host interface management and configuration.
This class provides static methods for discovering and managing network interfaces and IP addresses on the local system. It supports both IPv4 and IPv6 addresses, with configurable options for address selection and interface binding.
Key features:
- Network interface enumeration and discovery
- IPv4 and IPv6 address management
- Loopback address inclusion/exclusion
- Interface-specific binding support
- Host name and address resolution
This class is essential for UPnP devices that need to bind to specific network interfaces or discover available network addresses for device advertisement and communication.
