  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

Question Should I remove the ipv6 of my server from trusted IP addresses of fail2ban v0.9?

New Pleskian
I have new Plesk Onyx server with CentOS 7. I installed the Fail2ban component (the version installed is v0.9.6).

In the fail2ban.log I see a lot of warnings like this:

Code: 
WARNING Unable to find a corresponding IP address for xxxx:xxxx:x:xxxx::: [Errno -9] Address family for hostname not supported

The ipv6 is the one of my server and I noticed that is in the trusted IPs list. I know that fail2ban v0.9 does not support ipv6.

Should I remove the ipv6 of my server from the trusted IP addresses to avoid these warnings? Thanks for your help!
