Edward B. Dreger I thought of that, too. However, that would require NAC renumbering an entire /17 because an ex-customer is too lazy to renumber a /24.[*] If NAC's ex-customer thinks renumbering a /24 is excessive, what about something two orders of magnitude larger?

Indeed, but that's not the worst part. Should this happen, it would mean that the ex-customer just got PI space for free. Then the floodgates would open and a bunch of "why-not-me-too" would sue their ISPs to transform their PA block into a free PI block. Michel.
