The registries, ARIN/RIPE/APNIC should announce the offending block themselves and shunt it to null0. If the offender announces a /18 then they should announce theirs as 2x/19s and thereby override the bogus /18.
While a novel idea, I believe it is particularly dangerous to have an allocation registry strictly control operational use. A separation of power between the allocation and the dynamic-real-time use of address space is beneficial for many reasons. Historically, this separation of power has been maintained. For example, Sprint/smd's draconian filtering and aggregation policies were synergistic with address allocation policies, however, allocation rules were based upon different enforcement methods. Allocation registries allocate 'temporary ownership' of address space, without any respect for routability of address space. Allow the ISPs to police themselves, perhaps with assistance from ARIN/RIPE/APNIC. If they choose not to police themselves, that is their prerogative. I would support an available list of routes or BGP feed of allocated v. unallocated space, which ISPs could subscribe to so as to self-police proper address usage. In fact, it's unclear to me how ARIN could affect the routing of others, without dictating that ISPs respect their announcements. And I certainly would not want that. All in all, this proposal is flawed for many reasons. The goal of keeping the internet from splintering and properly using allocated space is a good one. This proposal is not the right way to help achieve that goal. -alan Thus spake Hank Nussbacher (hank@att.net.il) on or about Thu, Feb 15, 2001 at 07:31:52PM +0200:

Any time a network is caught announcing non-allocated address space, the registry should bill them accordingly. If they refuse to pay, the registry should yank their ASN. That would be strong encouragement to do the right thing.
Other than making it difficult for people to figure out WHOIS using that ASN, "yanking" an ASN's registration has little practical effect. You can use an un-allocated ASN almost as easily as using an un-allocated address block.

I don't think the problem is so huge that a few dozen extra prefixes announced by the registries will bloat and kill the routing table size. If the registries don't do this, these cybersquatters will come thru later on and demand to keep the IP address space they have grabbed just as the .sex, and .web and all the other alternate DNSers have done.
