I see. So I would better keep reading more… thanks
You could post the content of your
resolv.conf here, if you want. Might help explain; Might make things more confusing.
If speed is what you are worried about, there are several Opennic servers you could use: https://servers.opennicproject.org/. You could ping different ones, see which is fastest.
You can edit
resolv.conf manually if you want, it only says that because it may be overwritten by different network daemons (not sure which). But edit it and try out different DNS servers if you want.
was the quesrion properly answered? do you need further details on our infrastructure?
