    A quick way is to see which attribute has the IP assigned.

    1. lsattr -Elen0 -a netaddr -a netaddr6
    netaddr 170.154.108.234 Internet Address True
    netaddr6 IPv6 Internet Address True

    You tell it what to use when you first configure TCP/IP. Most people out
    there still use v4.

    I'm having a performance problem with Java when i open a Socket.Java uses IPV6 as dafault and if i use the System parameter -Djava.net.preferIPv4Stack=true the problem is solved. I suppose that if i set IPV6 on en0 so i wil resolve the problem. What do you think? Is autoconf6 the command to use?
    Thanks in advance

    something different?

    This Infocenter URL (bottom) has some steps for you to go IPv6.

    It sounds like you found the solution to your problem with the flag, so I would not go to IPV6. This adds new wrinkles and so could create new problems for you in other areas. So just use the flag to start your Java. It really does work.

    Why you prefer the use of the flag and not set IPV6 to the network interface?
