The smaller subnet in IPv6, if you want to keep autoconfiguration and other things working, is /64, so why you want something smaller coming from the RIRs ? In addition to that, if you want to allow subneting for your customers and your own network, you need extra bits for that. So that's why typically you will get a minimum of /32 block from the RIR and customers will get a /48 from you. Regards, Jordi

1.) get ula-central and know for sure we won´t get into this issue ever again.
2.) administrate our own local version of ULA-central for the organization we co-operate with
3.) get RIR-space with all the add on administration and documentation... For me, only option 1.) is a real option, the other two are just work-around since we don´t need global routing of the address space in question.
The RIRs already provide globally unique address space. This is what you want. Both ULA-C and the RIRs do not guarantee global routability anyway.
ULA-L is never globally unique, so basically there is no such thing as "Unique Locally Assigned" addresses.
Q: Is it correct that you can get a /26 IPv4 PA block, but you can't get a /96 IPv6 PA block? Why is that?
Cheers,
J
