This could also be refined. Not all 2001::/16 has been delegated to RIRs. ARIN got a block, RIPE got a block, APNIC got a block, but there still is some undelegated space. The drawback of refining to that level is that it will inevitably induce a situation similar to 69/8 and will require maintenance, but the other side of that coin is that it would prevent people from hijacking prefixes from undelegated space.

Someone else already commented on this. As the address space is pretty sparsely populated, people still would be able to hijack addresses (like "2001:609::/32", which is adjacent to our /32, but right now just unallocated).

*whisper in ear* not after tonight when the bogon reporting gets active :) Things that it does cover already: - unallocated prefixes - wrong source ASN's Though ofcourse one could bypass that when using the registered source ASN. That could be detected if we knew every 'upstream' for that prefix... Greets, Jeroen
