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

Giorgio1

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!
