You can announce them anywhere you like. But you cannot assign them to end users outside outside of the region.
really? so i have a /16 from ncc and i spread it over pops in ams, lon, and nyc, but i can not have bgp-speaking customers in that address space in nyc? if true, that is soooo broken.
That is my understanding, at least. I asked this question to the RIR panel at the mic in Rome, whether and APNIC region ISP could (post APNIC depletion) set up a LIR in the RIPE region (or any other region), and allocate addresses from there and assign them to end users in their home region. The answer (which came from Geoff Huston IIRC) was something along the lines of «no, you have to assign the addresses in the service region from which they were allocated».
no - I don't think it was me (unless of course someone pops up with a video recording of me saying exactly that RIPE meeting! :-) ) I am personally of the school of thought that believes that addresses can be used anywhere on or off the planet, irrespective of which RIR provided the original block allocation or assignment. I don't think any other address management regime makes efficient use of either our common routing system or the underlying address plant.
If this was not the case, I would not have expected the APNIC depletion from significantly slow down the global rate of IPv4 delegations, only that it would simply shift from the APNIC region to other regions as IPv4-hungry Asian providers started allocating from other regions. But looking at http://www.potaroo.net/tools/ipv4/fig09.png for example, this does not appear to have happened.
I was anticipating such a shift in demand myself, and I too am slightly surprised it has not happened. On the other hand I understand that if APNIC sees a member request from an organization with a home address from outside of the APNIC region there is a typical exchange of "have you considered using <xxx> as your RIR, as you appear to be outside of our regional service zone?" A typical response may be along the lines of "ah yes, but we intended to deploy these addresses in our in-region network". So I suspect that there is a defacto assumption made by many folk about the regional constraints of the use of addresses, but as far as I am aware it is not a rule that is applied by the routing system itself. regards, Geoff (speaking personally in this case, and I'm probably wrong anyway!)
