It is my personal impression that APNIC haven't got too much value to add in this discussion, they would probably like the addresses back, but don't really have any authority over what is and isn't do-able in the real world.
Except that you might want to consider what happens when you need to go back to them for more address space and you need to explain how well you've managed what you've already been allocated. You might also want to think about their http://ftp.apnic.net/apnic/docs/no-questions-policy.txt 2.0 The "No Questions Asked" Return Policy While it should be stressed that for the Internet to scale, all organizations should obtain address space from their service provider, pragmatically speaking addresses which were allocated historically ("legacy prefixes") have advantages for those who make use of them. Specifically, because legacy prefixes are historically allocated, they are unlikely to be subject to prefix length filters, thereby providing long prefix provider independence. In many cases, an organization will have multiple legacy prefixes all of which require independent routing entries. In order to help reduce the strain resulting from the continued growth of the default free routing tables in routers on the Internet, APNIC will exchange existing provider independent prefixes for a single provider independent prefix of equal length or one bit shorter (to round up should the amount of space not work out to a CIDR boundary) -- There are conditions but in some cases it's worth a look. The other thing you should think about is that when one one of your customers walks off to another ISP with one of *your* provider blocks then you've got no moral ground to stand on to complain about that behaviour. If you do advertise this you're punching holes in some other provider's supernet - try it from the other side and see how you like it. - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
