How can they justify taking 4 million addresses for research two days before running out of regularly allocatable address space? They could have taken that /10 out of the final /8 rather than taking it from the last scraps of regular space if they really need a /10 for research, which is already dubious in and of itself. Of course they didn't bother to respond to my request for information about all of this.
