I imagine this is fully intentional, and allows the NCC to grow my v6 address pool, without growing my footprint in the v6 routing table.
That is exactly what it is for. Then again, if you actually had *PLANNED* your address space like you are supposed to when you make a request you could have already calculated how much address space you really needed and then justify it to the $RIR. In case you have to go back to ask the $RIR for more you already made a mistake while doing the initial request...

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. :-)


% When will you use this address space?
%       Subnet       Within     Within   Within
%       size (/nn)   3 months   1 year   2 years   Purpose
