A similar problem with trying to ping valid hosts:

$ fping6 -C3 www.google.com
www.google.com : 0.00 - -

The problem with sending packets in this case is the following:

$ fping6 www.google.com
www.google.com error while sending ping: Network is unreachable

Thank you very much for the bug report. I really appreciate the effort that you put into analyzing the issue and reporting it.

I have fixed the issue in a slightly different way. Can you maybe test, if it works for you?

I have created a test release: http://fping.org/dist/beta/fping-3.9-rc1.tar.gz

Thank you for the fix! I have reviewed it and it seems to work.
