I need to disable IPv6. For that the java documentation indicates setting jvm property java.net.preferIPv4Stack=true.
But I don’t understand how to do it from the code itself.
Many forums demonstrated doing it from the command prompt, but I need to do it at runtime.
You can use
System.setProperty("java.net.preferIPv4Stack" , "true");This is equivalent to passing it in the command line via
-Djava.net.preferIPv4Stack=true
