Re: Operational Issues with 69.0.0.0/8... (fwd)

LDAP is where this kind of technology is going, I agree. But until such 
time as this is deployed, we'll still be using email and publishing 
information on the website. It can also be noted that those that create 
filters, have to get the information from somewhere - they most likely got 
it from email and website and these are the places where updates should go
(and on websites listing currently allocated blocks, there should be BIG 
notice that information here will change and those using it should come 
back and check on it every few months)

Also in my view it is responsibility of whever has the filters to keep 
them updated - they are taking a chance that this might not remove 
legitimate traffic (and take their time to create and deply the filter) 
and so they should have the time to maintain the same filter.

In my view the whole point of discussion here was that 1 month is NOT 
enough for everybody involved to know about new block being made available 
for allocations by RIR. What has been suggeted which is good is to have 
large RIRs (ARIN, APNIC, RIPE) keep one class-A on reserve ready for new 
allocations and when they begin allocating from such block, then there 
would be 6 month or year in advance notice about next block that allocation
would be made from. Such policy of having one "extra" class-a allocated to 
RIRs should be discussed by either ICANN ASO or by yet-to-be-formed NRR
(number resource registry).
