Well, we actually do have that mechanism in place: the registry database. It offers a granularity of (legacy, plus) allocations to LIRs and the assignments from within the PA blocks. In principle, this data should be reasonably accurate and should be maintained regularly. I presume at least the allocations, being maintained by the RIR should be pretty reliable? >From within the blocks, that's a different story maybe... But it should remain a scan and pull-technology by those who want to read and consume the data.

For some situations this could be a couple of times per hour, for mobile devices ;-) Other than that I'd suggest a frequency of once per day to pick up the new information. > Of course, we know similar demands from the domain business and these > requests aren't all free of concern, but the situation might be different > here in the addressing world. Yep, I think the discussion is useful, at least to start to understand what the expectations, the reality and the boundary conditions are! I always get back to see that resource distribution for the IP-world, for the Internet was never taking (volatile) national boundaries into account, neither on the administrative nor on the operational level. Maybe the parties trying to use geo-location to control access to information and (licensed) services should also start to accept that fact for their business model? > -Peter Wilfried.
