BIND : Verify Resolution2020/05/03
[1] Start and Enable BIND.
[root@dlp ~]#
systemctl enable --now named

[2] If Firewalld is running, allow DNS service. DNS uses [53/TCP,UDP].
[root@dlp ~]#
firewall-cmd --add-service=dns --permanent

success
[root@dlp ~]#
firewall-cmd --reload

success
[3] Change DNS setting to refer to own DNS if need.
(replace [enp1s0] to your own environment).
[root@dlp ~]#
nmcli connection modify enp1s0 ipv4.dns 10.0.0.30

[root@dlp ~]#
nmcli connection down enp1s0; nmcli connection up enp1s0

[4] Verify Name and Address Resolution. If [ANSWER SECTION] is shown, that's OK.
[root@dlp ~]#
