Nope, you are correct Geoff. There is a /10 reserved for transition technologies (e.g. outside addresses on a CGN) and there is a "critical infrastructure" reserve, but no general purpose reserve like in RIPE and APNIC.

One interesting thing is that this is dedicated specifically for transition/deployment of *IPv6*. So the way I understand it, you won't get any space from this block to number the outside of a NAT444-style CGN, while you would for a NAT64-style CGN. https://www.arin.net/policy/nrpm.html#four10 Tore
