Well, to increase chance of reachability of blocks immediately after RIRs start making assignments, RIRs should request new assignments from IANA well ahead of exhaustion of currently-held blocks. Possibly, considering that ARIN and RIPE run through 1 /8 a year, a "spare" /8 should be allocated to them (and filter-making folks dropping filtering). Smaller registries (APNIC, LACNIC), under this proposal, would request a /8 when their current /8 is 50% full. This should reduce frequency of required filter updates to once a year or less. -alex On Fri, 6 Dec 2002, Barry Raveendran Greene wrote:
IMHO - The RIRs are doing their part. They announce to the operations aliases their intention to allocate a new block before they start doing it. People like me (with the ingress-prefix-template), Rob Thomas (with the bogon template), and Steve Gill (with the Junos flavor of the ingress-prefix-template) start tweaking our templates and post them to the community.
After that, it would be up to each operations team to execute within their own network.

So for the sake of argument, in your proposal an ISP could filter all
of
the blocks that the RIRs allocate out of and hamstring them indefinitely?
Perhaps not, but an X month period after the inital allocation to the RIR where they don't assign out of that pool might be wise. Perhaps e-mails can be sent to the registered contacts of existing IP space upon initial allocation, on the first of each month, and then on the last day of the hold.
I know that I am sometimes a bit too busy to take care of something like that at the very instant I get the e-mail, and that it can fall to the wayside. Many times a reminder e-mail has come at a moment where I was able do to something about it.
