AFAIK, only Internode are offering IPv6; not sure if they are
dual-stacking it (ie, IPv4 and IPv6 together). There's not many DSL
modems that support it yet - I know Billion have one firmware for
one model that they released about 4 months ago - I'm still waiting
for an IPv6 release for my Billion 7800N, aparently now scheduled
for Q1 2011 (see [1]).<br>
<br>
As for tunnelling, I've been using HE's free tunnels for the last
year or so from my Debian box; my box is doing radvd on the local
subnet so workstations also pick up a routed allocation as well. I
have a cron script which runs periodically to ensure the tunnel is
up. Only down side with HE is that their closest tunnel end point is
(latency wise) Los Angeles.<br>
<br>
Some details for those wanting to play along, I have
/etc/network/interfaces with:<br>
<blockquote><b><tt>iface eth0 inet6 static</tt><br>
<tt> address 2001:470:f29c::1</tt><br>
<tt> netmask 64</tt><br>
<br>
<tt>iface henet inet6 v4tunnel</tt><br>
<tt> endpoint 66.220.18.42</tt><br>
<tt> address 2001:470:c:b5c::2</tt><br>
<tt> netmask 64</tt><br>
<tt> gateway 2001:470:c:b5c::1</tt><br>
<tt> ttl 64</tt></b><br>
</blockquote>
And a simple /etc/radvd.conf with:<br>
<blockquote><b><tt>interface eth0 {</tt><br>
<tt> AdvSendAdvert on;</tt><br>
<tt> prefix 2001:470:f29c::/64</tt><br>
<tt> {</tt><br>
<tt> };</tt></b><br>
</blockquote>
<br>
And my script which fires off to refresh the tunnel should I move
dynamic IPs on my DSL is:<tt><br>
</tt>
<blockquote><b><tt>HEUSER=deadbeef</tt><tt>deadbeef</tt><tt>deadbeef</tt><tt>deadbeef</tt><tt>

I was talking to WAIX about getting a tunnel endpoint here in Perth
and permit anyone to get a similar service locally; it may be some
time yet. I know iiNet aren't interested in offering IPv6. form the
people I have spoken to thus far.<br>
<br>
If you're looking to ping6 or browse to some stuff:<br>
<ul>
<li><a class="moz-txt-link-freetext" href="http://ipv6.google.com/">http://ipv6.google.com/</a></li>
<li><a class="moz-txt-link-freetext" href="http://www.ucc.asn.au/">http://www.ucc.asn.au/</a><br>
</li>
<li><a class="moz-txt-link-freetext" href="http://ipv6.james.rcpt.to/">http://ipv6.james.rcpt.to/</a> - my site virtually hosted in the
UK</li>
<li><a class="moz-txt-link-freetext" href="http://revo.james.rcpt.to/">http://revo.james.rcpt.to/</a> - my Acer Aspire Revo here at home
on the end of my HE tunnel - nothing on here</li>
<li>not much else....<br>
</li>
</ul>
<br>
BTW, If you're entering a native IPv6 address in Firefox, you need
to enter it inside square braces "[" and "]" as
<a class="moz-txt-link-freetext" href="http://">http://</a>[2001:470:c:b5c::2]/. If you have a non standard port, it
comes after the closing brace, as in <a class="moz-txt-link-freetext" href="http://">http://</a>[2001:470:c:b5c::2]:80/.<br>
<br>
<br>
One of the biggest disincentives for serious sites to support IPv6
is the lack of money opportunities - yep, that old chestnut. IPv4
has well established GeoIP that permits web sites to generate
revenue (thus supplying you with free or subsidised content) via
advertising. There are very few established IPv6 Geo databases
around - I think MaxMind have one. Compare to IPv4, where the free
Geo::IP is in most distros (country level only, but that's often
good enough) means that many web sites don't see any advantage in
supporting IPv6 - if the web sites advertising platforms only
support IPv4, then they'll not support you avoiding their
advertising techniques that generate them money.<br>
<br>
By money, I mean that a single click can earn upwards of $5 - $10
per click if you have good GeoIP and other targetting metrics - as
that leads to a high conversion rate (ie, a purchase of a product).
So we're not talking small change here. <br>
<br>
Thus, if the web sites you're browsing don't want this, then the
only people to get an advantage would be your ISP (via the ease of
getting v6 address space). They'll have to v6 -> v4 for you so
you get similar GeoIP IPv4.<br>
<br>
Looking at the top 25 sites visited in Australia [2], i've just
tested them and Google search is the only one I could find that has
a AAAA, and that's on a separate DNS name (ipv6.google.com, not
<a class="moz-txt-link-abbreviated" href="http://www.google.com">www.google.com</a>). So if you visit the "normal" published URLs, that's
a big 0%.<br>
<br>
Also, many home DSL routers don't do DNS lookups for AAAA. I've had
to explicitly tell my Billion router to hand out DHCP addresses with
the DNS server set to my Linux box. So even if people have a tunnel
set up, and RADVD running, if they're using their default DHCP on
IPv4 with their default DNS settings, they're not getting AAAA
records returned, so they never use the tunnel!<br>
<br>
Anyway, I think the sites that are next most likely to start to
offer their content over native IPv6 are those that don't use any
advertising, and aren't using any 3rd party metrics tracking that
can't be bothered to update. Government? Banking? Non profits? <br>
<br>
<br>
I lack the time to make this message shorter. HTH, HAND. :)<br>

HE also have tests / certification, not that it's industry regarded :P
IPv6 completely bypasses NAT and IPv4 firewalls, but it just means you need to configure an IPv6 firewall where each machine has an internet address...
Been dual homed on AARNet for a little bit, and on HE for about a year.

Subject: [plug] Exploring world of ipv6 - tunnels
I'm starting to explore the world of ipv6. Seeing as I'm on a telstra wireless
broadband connected, I'm double natted. I'm thinking that to best play with
ipv6 I need a tunnel somewhere. I know there are a number of tunnel brokers,
sixxs and gogo6 are the first that come up.
I also have a server that has a ipv6 address.
So my options are to use a tunnel broker, or setup my own tunnel to my server
and go from there.
Any suggestions (linux server and client)? What works best, easiest.
How secure are the tunnels?
Thanks
Tim
p.s. Using ubuntu, so tunnel software in ubuntu repo's would be nice</pre>
