Thank you for the clarification.  I think the staff practice is a reasonable 
approach and I don’t think change is needed in policy for this.

The updated Problem Statement reveals the real issue here - the one we need to 
figure out as a community.   What to do about all the requests each month for 
IPv4 addresses under section 4? 

Is it time to pass a policy to direct staff to no longer accept section 4 
requests (except the ones they still fill like critical infrastructure)? I 
wonder what the downside of such a policy would be - anyone know?
