Alerts - DNS server settings changed

I have many Alerts for DNS server settings changed, DNS address connection Realtek PCIe GBE family controller was changed. Old , New fec0:0:ffff::1 and then 2 sec. later it switches back to original. Happens once or twice a day. Is this normal. What should I do?

It looks like your DNS is switching between ipv4 and ipv6. You can go to the top left GlassWire menu and choose “settings” then choose “security” then choose “dns server settings monitor” and disable the alert.

it may be more helpful to be able to mark these addresse as trusted and not throw alerts for those, because you may want alerts otherwirse.

Yes, I agree that we should have some way to input trusted DNS.
