> Hi Nux,

> It is because NetworkInterface.getInterfaceAddresses() returns the ips in
> reverse order.
> For example, "ip addr show dev eth0" shows the following ips
> inet X.X.X.X
> inet secondary Y.Y.Y.Y
> inet6 Z:Z:Z:Z:Z:Z
>
> Then NetworkInterface.getInterfaceAddresses returns
> Z:Z:Z:Z:Z:Z
> Y.Y.Y.Y
> X.X.X.X

> The following patch should work as you expect.
