From the DSN part of your question I gather that you've been using ODBC and you had to set the DNS up.

With DBI you do not have to do that.Just use the server name straight up(if you have made the correlation to it's ip address inside the client's host file,so it is able to look it up)and the database name

As marto suggests look up the DBI docs.
