 \b0 If you plan it right, you should be able to supernet your subnets, and have one route or rule for them.  For example, you may have your networking equipment in 1-63, and your printers from 65-127.  That means you can have one route or rule that matches all 128 IPs.  This makes life a lot simpler for creating many sorts of rules.\b\par
 Smaller routing tables require less management and resources.\par
 \b0 Again, with the onset of more powerful routers, firewalls, and faster networking speeds, this is no longer quite as critical as it once was.  But if you have a finely tuned firewall, you can end up with many rules.  Often it is very nice to block all access to a whole range instead of blocking access to each machine one IP at a time.  Often, the "less management" simply means less work for the techies who are keeping things running smoothly.\par
