How to resolve named[*: network unreachable resolving in directadmin

systemctl status named
OUTPUT is:
Oct 24 04:51:03 * named[1587]: network unreachable resolving '*/A/IN': 2401:*:400::1#53
Oct 24 04:51:03 * named[1587]: network unreachable resolving '*/A/IN': 2a01:*:400::1#53
Oct 24 04:51:03 * named[1587]: network unreachable resolving '*/A/IN': 2001:*:ad09::3#53
Oct 24 04:51:03 * named[1587]: network unreachable resolving '*/A/IN': 2a01:*:404::1#53
.
.
.

And I saw this resolving method in some of the websites
vi /etc/sysconfig/named
OPTIONS="-4"
Then restart bind:
service named restart

but in my Linux Debian base OS this file doesn't exist
and I found this file /usr/local/directadmin/scripts/named

can I do the upper method to resolve my problem? or I have to use another method to resolve that?

UP! and be ready

Oh wow, I did a search on Google with "do not use ipv6 bind debian" and two first answers seem to resolve this.
Check them out:
https://jonkristian.no/disable-ipv6-bind-debian/
and/or
https://serverfault.com/questions/8...e-errors-despite-having-disabled-ipv6-in-bind (2nd answer with the green V below it).

No guarantee's, I'm using Centos so it's just what I found, not tested.

P.s. I do hope you're using an ipv4 for your server and port 53 is opened in the firewall and the ipv4 are setup as nameservers.
