当我尝试使用IPv4地址创建套接字时,它很成功,但是当我尝试使用IPv6地址和端口号创建套接字时,它会引发异常：

java.net.SocketException: Network is unreachable: connect

码：

我通过Eclipse IDE从Windows机器运行代码.

if(p_objSimData.getIpAddress().contains(":") )

{

System.out.println("IPV6 Address Found\n");

InetAddress ip6addr = Inet6Address.getByName(p_objSimData.getIpAddress());

System.out.println("InetAddress ip6addr = "+ip6addr); **//prints //2011::11 - IPv6 address**

objConnection.m_objSocket = new Socket(ip6addr,p_objSimData.getPortNo()); - **here it is throwing an exception**

}

else

{

objConnection.m_objSocket = new Socket(p_objSimData.getIpAddress(),p_objSimData.getPortNo());

//m_hmObjConnection1.put(p_objSimData.getIpAddress(), objConnection.m_objSocket);

m_hmObjConnection1.put(p_objSimData.getIpPort(), objConnection.m_objSocket);

}
