根据 IP 查找机器名

有时候ping -a 都不行
可以试试

pathping localhost

--------------

ping -a localhost

InetAddress addr = InetAddress.getByName("16.173.244.212");
		    
	        // Get the host name
	        String hostname = addr.getHostName();
	        System.out.println(hostname);
	        // Get canonical host name
	        String hostnameCanonical = addr.getCanonicalHostName();
