insane: I would imagine that Orcon and any other ISP in NZ for that matter still have enough unused IPv4 space they they are in no short term danger of running out. APNIC was allocated another /8 not so long ago so there should be a fair bit around still to come.
Wasn't it 2 /8's?
I may be wrong but as far as I know only Vocus offer IPv6 international connectivity, and they do dual stack v4 and v6 so it does put a constraint on your connectivity options.
I for one am not looking forward to providing an IP address over the phone, specially if not in the shortened form.
Why would you provide an IP over the phone? I imagine in the future you'll do other things (visit a webpage which logs details for the helpdesk, use a DNS entry, send an email) - plus with there being enough IP addresses for the entire globe, in theory you'll have static IP's for everything.
Even your fridge .... ;-)
