Hello,

- How do I get IPV6 addresses for my home? I doubt I'll get any as it
looks like I have to wait until the ISPs catch up. I have a Go6
tunnel but it gives me a /128 (I may need to do a lot more reading
as some imply that I might be able to get to my other device from
the V6 network).

For local IPv6 connectivity only, you can use "Unique Local IPv6 Unicast
Addresses" as described in RFC 4193. For global IPv6 connectivity, you
can use 6to4 addresses with automatic tunnelling, or another
point-to-point tunnel broker which gives at least a full /64, such as SixXS.

I have g06.com as my tunnel service. A few days after posting this I
reread the tunnel instructions and found I could set my end up as a
router. I'll do that later after I buld some proper iptables. I also
found the RFC and a script to help generate the addresses. Thanks.

- What IP address should my IPV6 apps bind to?

The one you decide according to your needs. I cannot be more precise
without further details.

I was afraid of that. I'll need more experience to figure out what to
use and what not to.

I've got djbdns working with IPV6 but one of its apps binds
it self to an address like: ::ffff:127.0.0.1:53 (IPV4 Mapped
addressing) but this is not one of the IPV6 addresses that I have on
my interface.

IPv4-mapped IPv6 addresses are used for IPv4 communications on an IPv6
socket, i.e. the socket is IPv6 but the actual packets are IPv4.
::ffff:127.0.0.1 represents the IPv4 loopback address 127.0.0.1. If an
application binds only to such an address, it will allow only IPv4
communications.

Thanks I hadn't figured that one out yet.
