Yeah i get that. But if you dig @opennicIP, you skip the resolv.conf. So
it does not matter what you system "normally" uses.
So whats weird here is that the output changes, denpending on the server
you configure on the Pihole. This should not happen and leads to thing
me that something (perhaps your firewall) is somehow messing things up here.
