The tool will accept a number for the count of IP addresses to be assigned
and search for a suitably aligned assignment. Obviously you will end with
holes in your allocation whenever an assignment is returned.

There are various alogrithms (coming by memory or disk space allocators)
that try to get 'optimal' results by filling the holes. This tool does a
two phase search, first it looks for assignments that fill holes completely
and then it falls back and searches the first hole in the allocation that
is large enough.

Why not ? Most assignments are completely arbitrary. There are two
reasons to chose a specific subnet: aggregation and reservation.
In both cases you do a bigger assignment first (which only exists
privately, not in the RIPE database) and select your assignments
from this block.
