If a large network with large amounts of nonportable space, like UUNET, were to fail entirely (financially, or system-wide, e.g.), what would happen to the address space that that network had assigned to its customers? When those customers go elsewhere for access, would the routing tables be flooded with /24's? Alternately, would that space be reclaimed by the registries, and all of those customers be forced to renumber? How long would that take? In a similar vein, how would the DNS act with millions more lame delegations? (And what if all of the root servers were smurfed under at the same time? ;^) If this has been discussed elsewhere, I apologize for the bother, and would appreciate a pointer to that discussion. --- Mark R.
