I understand that a SQL server named instance will default to dynamic ports, and I know HOW to change that to a static IP: http://blogs.msdn.com/b/sqlserverfaq/archive/2008/06/02/how-to-change-the-dynamic-port-of-the-sql-server-named-instance-to-an-static-port-in-a-sql-server-2005-cluster.aspx
BUT, I'm still wondering what that dynamic range will be?
