Hi Sander, So what is it that you and Andrew see in the net-pgm draft or the SRv6 proposal that lead you to believe such a change in the IPv6 assignment or allocation sizes are required by RIRs?
I am assuming this is the same "IP Space burn" topic that Andrew alludes to ...

Now, I don’t claim to be aware of Softbank’s current and future > use-cases. I don’t think it is a topic for discussion on an IETF mailing list. I disagree. I think the RFCs that the IETF produces should be deployable in the real world, and where that requires changes at other organisations in the internet ecosystem like the RIRs and their communities that requires cooperation, communication and consideration. The IETF does not exist in a vacuum. To help start the discussion and awareness, I just made a list of all the IPv6 current assignment and allocation sizes in the RIPE NCC service region: /19: 3 /20: 2 /21: 2 /22: 2 /23: 5 /24: 5 /25: 5 /26: 8 /27: 11 /28: 7 /29: 11614 /30: 107 /31: 54 /32: 6346 /40: 1 /42: 1 /43: 1 /44: 2 /45: 7 /46: 17 /47: 39 /48: 2998 This is the operational context that these standards exist in. If anything needs to be changed that will need cooperation with the RIR communities at the least.
