I use Stubby, however, I have a vlan2.
When installing stubby it activates the option 'Ignore resolv file', and in vlan2 I have set the option 'Use custom DNS servers' to 4 alternative dns addresses.
Question is: When I activate 'Ignore resolv file' do I lose router cache on vlan2?
And what is the difference in the practice of the 'Use custom DNS servers' and 'DHCP-Options' options?
