Original GH issue: https://github.com/openshift/openshift-docs/issues/673 Need better guidance/examples on you might configure a suitable DNS environment. See above Issue for details.
Also adding https://github.com/openshift/openshift-docs/issues/675 here (about ensuring hostnames are set correctly) so that they're addressed together: "I think more detail is required to help people avoid trouble if they are pointing to outside dns server or have incorrectly setup FQDN on their master and nodes." See above Issue for details.
