Class NetUtil

  • public class NetUtil
extends Object
    This class is taken from the Netty project, and all credit goes to them. It has been modified, to remove dependencies on other classes, and to convert to methods, rather than a static value. The getAllLocalIPs() method was taken from the Apache Curator project which is also under the Apache 2.0 license.

        Returns all available IP addresses.

        In error case or if no network connection is established, we return an empty list here.

        Loopback addresses are excluded - so 127.0.0.1 will not be never returned.

        The "primary" IP might not be the first one in the returned list.

        Returns:
        Returns all IP addresses (can be an empty list in error case or if network connection is missing).
        Throws:
        SocketException - errors
