DataNode: what to do if DNS is not working on Dev machines?

SSL cert creation certainly makes more sense if you have a working DNS so you can add the correct CN/altNames. At least for Prod systems.

On at least one occasion, DNS was not working correctly on a developer machine so there was only always the IP address coming back. So far, we do not add IP addresses to the altNames, but we can.

Is this something we want to do or do we consider a DNS problem sth. that has to be solved first?

After some thoughts: I think, the solution should be to put sth. working into `/etc/hosts`
