As far as I remember the IPv6 policy discussions on the last RIPE meetings, one thing that was voiced repeatedly was
"if we have to hand out /48's to customers, a /35 for the LIR itself is not enough"
(considering hierarchical strutures - either due to multinational networks, or due to hierarchies of resellers having re-selling customers themselves - 13 bits to work in is just not enough).
Also, it hasn't really been shown why we need slow-start *in slow-start space*(!). It's not like we want our own TLA, but I think the RIRs are being way too conservative. Old IPv4 habits...?
This was certainly the concensus also of the GEANT IPv6 Working Group, the opinions coming from representatives of the National Research Networks in Europe. At a minimum we would expect the removal of slow start /35 to offer /29's. Moving the bit boundaries is a secondary concern, but one worth considering sooner rather than later. It is not clear that a /48 is sufficient for a university with satellite locations and that also feeds local colleges/etc, and that offers remote access to staff and students. Thus a national research network would struggle within a /35. Recommendation #2 of http://www.enigma.ie/articles/global-ipv6-alteration.html is a minimum requirement. As a group, we have not discussed more ambitious suggestions such as those at http://www.djp.net/ipv6/proposal.html where a /16 is suggested for the "supernational" organisations. Tim
