Thanks all, I knew this must have been seen before.
I agree the feature would be nice.
Furio your situation is much like mine.  400,000 ip's in a few thousand 
various sized CIDRs that this one ISP "owns".  They all need to be 
excluded from their RBL check.  It changes daily too.  rbldnsd can 
handle that much, as 400,000 individual exclude ip's but it's a bit 
painful.  Making a script to only expand /8 and larger just makes it 
harder to script too, and not much smaller.
