/48 for each and every endsite (Was: European ISP enables IPv6 for all?)

[Jeroen Massar <jeroen () unfix org>]

Changing subject for these replies which will definitely be a bit on the
quite mean side... no offense but start reading for once. Next to that
there are also LIR courses which cover all of this.

(see other mail for /56 for end-user-sites, /48 for end-business-sites)

Can I read from this that you never actually read any of the $RIR policy
documentation about getting IPv6 address space even though you did
request a /32 before, clearly without thinking about it?

"new" as in "We already have one, but we actually didn't really know
what we where requesting, now we need more"

This explains quite a bit why people are looking so weird when certain
other organizations get a /20 and upward from $RIR.

My suggestion: start reading.

That would be stupid and totally against the idea of IPv6.

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...
