I was afraid this argument would come up as soon as we take one step from the strict 8+8 structure of IPv6. This is not a valid argument. There is never a good reason to give anyone a /64. (I'm talking about customer relationships here, of course not about single IPv6 subnets.) Giving out a /64 in a customer relationship is a form of fraud. It is akin to renting the door to an apartment separately from the apartment. Yes, of course you can live perfectly fine in an apartment without a door, so you *can* price-differentiate between apartments without doors and with doors, but renting one without a door is still fraud. The smallest address range that should ever be given out to anyone is a /56. /60 may do in a pinch (like the one experienced by free.fr), but that is already stretching it. Folks, if any of your rollout plans involve handing out /64s to another entity, you have to reconsider. Sorry for this strong reaction, but any scheme to get multiple subnets out of a /64 runs so fundamentally counter to IPv6 principles that it needs to be quashed quickly and effectively.
