There is a pretty comprehensive list of the delegation status of blocks at the /8 level that is pretty accurate. I suspect that the RIRs can provide pretty good detail for the recent (1996 and later) delegations. The historical delegations are -much- harder to track. I've been spending some time on clearing up detail on older /8 blocks and this data may make it into the publicly visable registries if they want it. 128.0.0.0/8 is done and I've got most of 192.0.0.0/8 complete. -- bill
