The number of globally routed addresses is not directly related to the 
number of resource records that need to be included in a zone.  ;-)

I would only include resource records for IPs that are actually in use.

Just because an address is routed, does not mean that it's in use, much 
less that it needs to be in a zone.  Hence why I asked if the number of 
globally routed addresses is really the problem.  }:-)

If I could trivially fabricate records for IPs that aren't in use and 
not require unreasonable storage, then I would.
