iperf doesn't do IPv6 by default
A means to measure network responsiveness and throughput

As reported to Debian Bug Tracking System: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1000349
iperf uses ipv4 by default even when only ipv6 is available, that's a bit weird.
I think it should do the same as standard utilities: bind to ipv4+ipv6 by default and use -4 option to force the use of ipv4 addresses when both ipv6 and ipv4 are available.

I opened a ticket for a proper fix. I'll be adding -4 to support v4only per that.
Here is a fix for the v4 regression.

Thanks for the reminder. I'll plant to get this fixed prior to the 2.1.9 release.
Hi, I've just tried 2.1.9 and I think this is not fixed :-(
sorry, didn't get to this in 2.1.9. I'll try to get to it soon.
