Routers would ship with the iana_reserved_block list of when they were manufactured. If the user is stoopid enough not to be able to get his filters from Cymru directly then he should not have any filtering at all because he is never going to update it anyway in the future. Ergo lots of black holes for newly allocated address spaces to the RIR's.
Exactly. (Unless "IANA reserved" != "unallocated" but IANA does call unallocated space "reserved".)
The cure will be far worse than the disease if routers would come with pre-configured bogon lists.
Indeed. In fact, the whole bogon filtering thing is more harmful than useful.
If you do any bogon filtering at all then do it with some automatically updating system like an BGP bogon feed from Cymru.
What exactly does this feed do for me? Wouldn't bogons be everything that isn't in the global routing table?
