If you are stuck - you can change your network topology a bit.
1. Do IPv4 internally using Internal Network addresses.
2. Only give the public IPv4 address to folks who pay for it & meet ARIN
justification for the IP (amazing how that helps quite a bit ;-) )
3. Utilize a public IP for those Natted clients
4. Utilize a 6to4 tunnelbroker (unless you have your own IPv6 dual stack
running.) both SixXs and HE.net offer this service and provide FREE BGP
routing if needed as well.
5. Run your own 6to4Nat implementation. While its a little bit of a
struggle to get there - you can do 1to1 Nat worse case - well technically IPv6
does not support NAT - so let us call it what it really is - it's a "private"
tunnel.
By building your own tunnel and using at minimum linux 2.6.22 or above (older
kernel will simply not work) - you can utilize the iproute2 package and voila -
your problems are solved (well it takes work... ) Cisco routers support
automatic 6to4 ISATAP as does Vyatta and many other routers now.
I did a posting recently to UBNT asking when we can expect IPv6 from them -
asked for a drop dead date... sadly have not seen that yet ;-( instead got a
"coming soon - a few months" response.
One important note - there are disadvantages of 6to4 relays such as the
probability of asymmetric routing so unless you know what your doing - stick
with Sixxs (if based in Europe) or HE.net (if US based) as a broker.
On the plus side - my tunnel from Hurricane Electric www.HE.net (free) is
actually lower latency to some parts of the world than my IPv4 route and almost
always less hops.
We have some servers @ Linode, some in our own data center here in Ohio, some
in Texas and others in the UK - and the IPv6 Tunnel does some wonders for
latency and routing between them ;-)
This may be due to the fact that HE is on of the top 10 (actually # 6)
networks in regards to peering. Currently according to fixed orbit - HE.net
has 1385 networks it peers with - (More than Sprint, More than Road Runner -
More than Comcast... and are beat out only by a few others.
(to note the top 10 are as follows:)
#1 Level 3 with 2703 peers
#2 Cogent with 2696 peers (and folks keep bashing them saying their peering
sucks... go figure)
#3 AT&T with 2332 peers
#4 MCI/Verizon with 2009 peers
#5 Global Crossing with 1390 peers
#6 - HE.net with 1385 peers
#7 Qwest with 1377 peers
#8 TW Telecom Holdings (not Time Warner Cable / Road Runner ) with 1326 peers
#9 Sprint with 1316 peers
# 10 Init 7 AG with 958 peers
(note those are direct peers )

What is working stays working.. yeah if you need to put a new 1000 Wifi
routers.. very likely then you will need to put up the ones that support
IPv6

So what is the solution if you have 1000+ WiFi routers that don't support
IPv6? Pretty penny to replace.

There was a requirement to use with IP allocation. (would need more
within 3
months, if not allocated, or something like that).
There is a legal basis to make IP holders return IPs that they are not
using, or will not use within X months.
Selling it on the secondary market is not the intent of the ARIN original
rules, regardless of what recent decissions ARIN may have made..

Probably not directed towards ISPs, but to other organizations.

GE probably doesn't need 16M+ IPs.
HP probably doesn't need 33M+ IPs.
Ford probably doesn't need 16M+ IPs..

No, it's not a real problem. I liken it to the exhaust of
homesteads in
the
past century. You used to be able to go to a land office and ask
for
your
40 acres. Then they ran out. But you could still buy a farm from
somebody
who previously had a homestead.
Very few are going to give up there 'old' IP space without wanting a
high price if at all. I know I won't, any one else going too? Like
most ISP's we grow every year not shrink. I see this as a real
problem. I imagine we will dual stack soon and when the pinch comes
give lower tier users a NAT'ed IPv4 IP and a /48 or /64 of IPv6 space.
I hate the idea of handing out NAT'ed IP space though. Too hard to
tell who did what. My opinion is there should be a very hard push to
IPv6.
Whats bad is 99% percent of consumer wifi routers do not support IPv6.
That is going to be a HUGE issue.
