Re: 90 IPv6 sub-TLA allocations made

The last reply from the RIPE NCC hostmasters said, "Because Supernational Registries may not receive multiple IPv6 allocations you would need to have allocated 80% of the networks in your current sTLA before we could issue more address space."

Please forgive my ignorance and allow me to ask, "where is it written that Supernational Registries may not receive multiple sub-TLAs?" Is this a RIPE NCC interpretation of the bootstrap criteria or is it actually written down somewhere? /david
