I think you're asking if it's possible for OpenStack to handle registering each public IP assigned to an instance with a DNS service so that each instance can be accessed by a hostname such as (instance name).mydomain.org ?
I don't think OpenStack handles this today. If I were trying to assign host names to instances, I would look at a script installed into the instance either as part of the image or part of the first-boot setup. I used a program called 'ddclient' in the past to do this: http://sourceforge.net/p/ddclient/wiki/Home/ It also appears to be included in at least Ubuntu distributions today, the other major distributions probably have something similar.
