[AusNOG] Final /8 allocated to APNIC from IANA (103/8)

[John.Gibbins at csiro.au]

If it costs money to keep them and they are no longer needed, I expect they will be handed back.  Whether they will no longer be needed in five years time is the big question.  

If we returned all of our IPv4 addresses, it would drop out APNIC fees by about 90%.  Unfortunately due to the logarithmic charging scheme, we would have to return a very large percentage to make significant reductions in cost. I can't see that happening within 5 years.  It would take us that long to migrate systems off IPv4 after we decided that no one else on the Internet was only on v4.  Maybe in 10 years...

I don't have a feel for how fast the last /8 will be handed out, so I have no idea whether it could last that long.

Very interesting point, are we going to see IPv4 addresses handed back
say in 5 years once IPv6 is in full swing?
