fail2ban now supports IPv6 - please upgrade
At some time you closed the request "fail2ban for IPv6" stating that fail2ban does not support it. That was no doubt correct at the time - but now it does, see https://github.com/fail2ban/fail2ban/tree/0.10
I'm seeing a lot of warnings in the fail2ban log on my dual stack servers, like this:
66:1000:b01c:10ab:0:1: [Errno -9] Address family for hostname not supported
and my log checking software is complaining to me about the overly long fail2ban log.

Available since Plesk Onyx 17.9 Preview 7.
Keep voting this is importent. My host ovh now added ipv6 to all there servers by default andwe need acway to defend our server.
Add fail2ban for IPv6
