69/8...this sucks

Look, there's no quick fix solution here.  It's going to take real
effort and real work.  However, the _REASON_ all those pages reference
sample bogon filters is because there isn't a global bogon filter
that is dynamically updated available.  If there was, and people were
aware of it, they'd use it.  (At least a significant percentage would).

As such, is a BGP feed a panacea?  No.  Is it a step in the right direction?
Yes.  Will it solve the problem by itself?  No.  Will it improve the 
situation?
Yes.  Moving the root servers into that space may expidite solving the 
problem,
but at a _VERY_ significant cost.  Moving the GTLD servers might make a 
little
more sense (at least then, you aren't requireing _EVERYONE_ to update their
hint files), but I still don't think that's a good idea.

Others have suggested that it needs to be available in LDAP.  Some have
suggested DNS.  As far as I'm concerned, the same servers or some group
of servers could easily be set up to publish the authoritative BOGON list
via DNS, BGP, LDAP, HTTP(XML), FTP, and possibly other protocols.
Getting bogged down in the protocol isn't helpful.  Finding a way to make
an authoritative global BOGON list (Note: BOGONS are the 
UNALLOCATED/UNASSIGNED/
RESERVED/INVALID _LARGE_ blocks, _NOT_ every little hole in the allocation
space) that is dynamically updated _IS_ the most practical solution for the
long haul.

Renumbering multiple global resources every time an RIR starts issuing from 
a
new /8 isn't feasible.

Publishing the data over the net is.
