Yes, exactly.

In my opinion also the aggregating filtering on min allocation sizes
IP-Plus is doing is wrong.

The problem with default deny everthing unless allowed is always that
you have to readjust this kind of filter all the time. And you might
miss some update or you are on vacation or...

I deny </7 and >/25 plus the RFC1918 and DHCP space but allow everything
else. The risk to miss a change or new allocation is almost zero and it
works right away.
