Operational Issues with

OK, clearly this discussion has mutated into a couple of discussions.  I 
was under the impression we were still talking about a published list of /8 
delegations, since all of the prefix filters I've seen operate on that 

However, part of the discussion has mutated into how the RIRs should 
provide insight into unallocated space inside of delegations they have 
received from IANA.

There are several issues.  There is the operational issue relating to 
people who have received allocations inside of 69/8 and cannot get to 
backbones who are filtering announcements from that block.  I'd say it's 
safe to assume that the backbones who are filtering 69/8 aren't reading 
NANOG, so the fact that the operational discussion is happening here 
probably isn't doing much good to help Todd's problem.  As far as how to 
fix that, somebody probably needs to find the right person at these ISPs 
and use a clue-by-four appropriately.

Then there is the registry issue of how to provide relevant information 
about which /8s belong to which RIRs.  I respectfully suggest that people 
periodically query http://www.iana.org/assignments/ipv4-address-space for 
this information.

Finally, there is the issue of providing information relating to 
unallocated blocks within each RIRs allocations.  This discussion is far 
more relevant to the registry specific mailing lists.  I suggest those 
interested in discussing that join the appropriate ARIN mailing list.  The 
discussion is happening on ppml at arin.net, though it is probably more 
appropriate to the dbwg at arin.net mailing list.
