Doesn't surprise me at all. I take it, your position is that if an address can have a 64-bit prefix and a 64-bit host ID, then all you should need or want is classful addressing. And only one class at that. Does that sum it up? What's old is new again. We could almost revert back to RIPv1. I don't necessarily disagree, and I got that same message from others on the list in the past. And I also wouldn't suggest that prefixes shorter than 64 should be in heavy demand (except in assigning address blocks). It's just that the restriction seems unnecessary, especially given that /127s and /128s are already in use, that CIDR has been invented and everyone knows how it works, and also because the /64 restriction only matters for SLAAC.
