Hi.
Just because network addresses could be considered portable a few years ago doesn't make it so forever - the network is changing, and best current practices change with it.
True, but if you look at best current practice, that does not including route filtering more strictly than the minimum allocation size (i believe it was tried and rejected :-), and it does not involve restrictions on portability. It's easy to argue that within the NZGATE addresses the minimum allocation size is /24. There is also a very serious danger with trying to force this non-portability aspect. It reeks of commercial and not technical motives. It looks like a way to lock up customers by making it difficult to change providers. And without a serious technical reason (like if we don't do it, no one will be able to use the Internet), it is. If i didn't know Joe better, i would have suspected this was part of the reasoning. Nevertheless, one has to look as well as be very clean on any proposal in this area -- looking or behaving like a cartel will cause serious problems. I believe we can accomplish the basic goals with different rules, rules that are fair, fit existing practices, and have little potential commercial motive. How about we use: You can't move unless the entire block allocated by Waikato was allocated to you (or else you renumber). This allows ISPs to move about freely as suggested, some companies will also be able to move, but not those who obtained their IP addresses from an ISP. This will help prevent much further fragmentation, will help prevent overlapping advertisements, and helps clarify "ownership". It would seem prudent for us to at least look at the current allocations and estimate the amount of address space assigned to ISPs and to end users. I suspect there is only a small percentage of end user blocks. And if this is the case there would be very little practical difference between this and the draft's rules. -Craig --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
