Steve and/or Joy, could we get a verdict on this issue? The lack of a netmask
in the SPD audit messages is pretty serious so I'd like to see this fixed as
soon as possible.
I think Steve may be able to answer this much better than I can in
regards to audit. In my opinion having the netmask is good.
