/0, I guess.  It's not really a legitimate mask/address (which is why you're
trying to block it, of course), so how it's interpreted is going to be
application-dependent.

I'd suggest posting this on the ipfilter list ( ipfilter at coombs.anu.edu.au )
and see what Darren says - it really depends on how IPF decides to handle it.
