There are eight 4 digit external DNS servers under the DNS Preferences. You use the OpenNIC servers so does one add those to the list?
I travel frequently, usually to China where I use a VPN; do I update the OpenNIC servers when I am in China?
I think more details of the preferences are required for amateur users such as myself.
You have the opportunity to change the list according to your wishes such as delete or add new servers. The list is not limited with 4 servers, you can fill it with so many servers you wish
