With respect, Jeroen, because I did *PLAN* (your emphasis) our  
organisational requirements, this is precisely the reason why I think  
it's significant that a lot of space was left unallocated following  
my allocation.

My RIR only asked me to *PLAN* two years in advance (see ripe-414  
[footnote 0]), though prudent organisations may plan for longer.  I  
thought it was significant (and good) to note that they are allow me  
room to grow sometime after that period.

If you offer the sweeping statement that anyone who ever needs to go  
back to the RIR for more space has made a 'mistake' with their  
requirement planning shows you're only thinking in an incredibly  
short term manner.  Unless, of course, you are only used to working  
in companies which do not grow. :-)
