Can someone identify the *benefits* of using bogon lists for unallocated space? It appears that it only hurts connectivity, but does not help inany significant way to enhance security.
It might be a way to proactively keep your part of the network 'cleaner' than the other parts... 'managed' properly and 'updated' regularly (when changes dictate an update is required) it might even be seemless to youruserbase.
The devil here is, as always, in the details. Once you move beyond somenumber of devices or acls or 'parts', making changes on a wide scale andkeeping things up to date becomes more difficult.
I've never been a fan of bogon packet filtering (bogon route filtering is more useful), but it occurs to me that it's probably better for us network opertors to do this rather than have each and every firewall admin do it for themselves.
I.e., in networks that do proper BCP38 filtering towards their customers and bogon filtering on the edges to other networks, customers will never see packets from bogon sources, making it unnecessary for them to filter those themselves and thereby improving the plight of those who get address space that was recently allocated to a RIR by the IANA.
