They can't really make *sure* of it, any more than with any other prefix.... I think there is language to that effect somewhere. That said, I think ARIN does try to allocate these smaller allocations from a block that is less likely to be filtered (by most networks). > Yes, minimum assignment is /20 (and this is considered temporary, as the > official minimum is /19) -- there used to be some experimental /24s, > but I believe these are now gone.

Could be wrong, but my understanding is that they will allocate a /22 or shorter when the requesting org is multihomed. http://arin.net/policy/nrpm.html#four222
