it's pure profit, you understand that, right? arin charges like 1000$/year 
for /20.

ipv4 had 'flag day'. when the old protocol was disconnected and everything
was switched over to ip. clearly, the interwebs was smaller then. [just a 
history lesson]

Until RIRs say "we cannot give you any more IPs", there's no problem at 
all. Everyone can get IPs today. Thus, nobody feels the pain.

What's that have to do with anything? are you saying that people in taiwan 
have v6-only connectivity and unable to communicate to v4 sites? [for the 
record, i do believe there are some providers who give by default both v4 
and v6 ips. i don't know any provider in any country who'd give v6 only ip 
and 6to4 for the v4 access].

i'm active in the nanog community (which is the network operator community 
- people who actually run the large networks, like l3, vzb, etc), and 
moderate the mailing list (yeah i know, alex as a moderator). v6 has been 
a staple of conversations for past 6 years. yet, it remains in sort of r&d 
phase - you can't buy v6 native transit from anyone. the best you can do 
is v6 tunnels. fun thing is asking the v6 presenters at the conference 
'so, can you sell me v6 transit' and getting giggles from them.

show me the benefit. show the business need. you say you want 65k IPs - 
what for?

there *is no production-grade v6*. at best, think internet in late 80s -
stuff that engineers tinker with, which goes down every so often. no large
carriers have v6 native ports to customers. NONE. Not one. On backbone, I
think there's *maybe* one that have v6-native-capable backbone - everyone
else has "overlay" network or tunnels. There are two that will actually
sell you the "v6 tunnels" to their tunnel servers (one per city). Everyone
else simply doesn't care. there's only a limited amount of peering (for 
example, as opposed to full mesh for tier1s, there are maybe a couple of 
peering relationships, not in all geographic regions etc - resulting in 
your packets likely traveling halfway across the country multiple times).

since big boys dont care, it is engineering-heavy providers that try to 
make something sort of work. he is doing their piece. occaid is providing 
"ghetto backbone" for ipv6-enabled customers. but it is really tunnels 
over v6 network which are held together by spit and glue, running over PC 

i'm just telling you 'how it really works'.

i don't see anyone listed. nobody cares, apparently.

we can. for us, its not so much of a big deal - our equipment supports it, 
and we can probably interconnect with occaid for v6 "backbone", and I 
think one of our transits might do v6 as well. so the expensive is X hours 
of engineering to make sure everything works as well as training my noc 
guys to know what v6 is (this is much harder than engineering).
