Re: New Draft Document: De-boganising New Address Blocks

>Address Blocks":

That is a misleading title.

The problem is that ISPs cannot react quickly enough
to open filters when new ranges are allocated. The proposed
solution is to provide advance notification. I suppose this
could allow ISPs to open filters before the new addresses
are actually in use officially.

However, it will also allow spammers to announce this
space and get it through bogon filters.

The real solution to this problem is to make it 
possible for ISPs to closely track RIR allocations
in their filters in a semi-automated way. There may
still be a few days of delay before a new allocation
is fully routable but ISPs can compensate for that
with internal processes. 

Why can't ISPs subscribe to a feed of all new 
RIPE allocations in near real-time?
