Either/or. As long as they are resolved exactly the same way for all nodes, it doesn't really matter during install/create. For the public stuff, I'm a big fan of both hosts and DNS - end users use DNS, but nodes don't need to do network hops to respolve. With local cache it shouldn't matter, but I've experienced hiccups due to DNS resolutions delays. OTOH, it adds burden on the admin team.
