Hi Mans,
I'm working at one of those organisations who have a /48 and am announcing it into DFZ. We have a situation where I might have another site with separate connectivity to the DFZ (but there is internal networking) which would entitle me to another /48 according to RIR rules.
Correct.
I did ask my LIR whether there is any thought given to the possibility of getting the next higher prefix, thus creating a /47. They did understand the "why" perfectly well, of course.
However, apparently there is no such process or intention available from the RIR in question (RIPE), short of explicitly asking for that specific prefix.
So you asked to grow the /48 to a /47? Was it accepted? Or did you want the RIR to automatically grow your first assignment when you request a second one without you having to ask?
Of course this does not help every case, but supporting aggregation where possible certainly ought to be in-scope for most policy-making bodies in this area.
Then please take this to the appropriate policy-making body: address-policy-wg@ripe.net :-) Cheers! Sander
