your comment seems to imply a relationship between the need to summarize
with area range and the type of mask in the network statement. There is
NO relationship. The mask used in network statement does not impact
summarization and does not impact what is advertised (OSPF will use the
subnet mask from the interface to determine what to advertise).
Having said that I will say that my personal preference is to use the
very specific mask. It is a little more work up front but I find it
more easy to troubleshoot and certainly may facilitate changes that
might need to be made down the road.
