Anyway, I've been wondering for a while - how many new ISPs (or LIRs, for that matter) have been founded over the last - say - 2 years? Given the technical requirements as far as performance and bandwidths go, and the low end user prices for Internet connectivity, I don't see how there are any feasible business models to start an ISP business nowadays... this poses the question whether saving v4 addresses for new ISPs/LIRs is even relevant ... plenty sufficient in many cases, though possibly too smal in some special situations with many servers), this isn't sufficient for the predominant use, multi-homing. Question is - as others have already stated - whether multi-homing is a valid reason for getting v4 addresses in this phase ... I reckon if the policy should be altered to allow v4PI assignments, should there be a quota between PI and LIR assignments? I've not read up on the amount of reserved space for future uses, but say that's 20%, should there be a 4:1 ratio between PA and PI, eg. 64% PA and 16% PI? Also, should there be some sort of regulation as to what businesses ought to be allowed to receive LIR status? Otherwise, regular end customers with enough money (or enough despair) could chose to become an LIR, wasting more space than they would getting (currently unavailble) PI space, with only one company profiting from /22, while "real" LIRs might not get anything at some point, with dozens or hundreds of end customers not being able to get v4 addresses ... -garry
