Quick question regarding the domain mapping plugin.

Just about to setup my first mapped domain later today once my DNS update to my server is completed.

My multisite is using subdomains with a dedicated ip/server. Would I be correct in thinking that any domain I map on to a sub domain, it is possible for the url to only display the mapped domain name as oppossed to the sub domain name.

eg - mapped domain energiavital.co.uk on top of energiavital.eevee.co.uk.

My client (energiavital) would like to have their proper url displaying when people navigate through their site. Is this possible?
