Address spaces
Hey debian-ipv6,
My questions are not debian specific but concerns messages I've been
reading here in the last weeks.
I'm in the process of choosing the IPv6 addresses of all my hosts, and
I'm quite lost because of the overwhelming possibilities.
I have normal IPv4 hosts with a public IP and I've setup
6to4 to them, as explained in Rob Leslie's message (#18 in
<http://lists.debian.org/debian-ipv6/2003/debian-ipv6-200304/>).
I configured ALL my hosts as "6to4 gateways", and I'm wondering if
it's the correct use of the architecture described in the message. I
understand the goal of these gateways only if I have one of:
- IPv6-only hosts,
- IPv4/IPv6 hosts with private v4 (only one public IPv4 on my
network).
However, I do not have any of these.
Another question that keeps harassing me is about ::w.x.y.z/96
addresses, I thought they were the official 6to4 addresses, but most
documents I read refer to 2002:w.x.y.z::/16 addresses.
Once I setup a 6to4 tunnel with a 2002 address, I see both kind of
addresses:
inet6 addr: 2002:8ac3:9c9b::1/16 Scope:Global
inet6 addr: ::138.195.156.155/128 Scope:Compat
Does that mean that ::w.x.y.z addresses are deprecated? Which one do
you advertise in your DNS?
I have a VPN with 10.x.y.z addresses, should I use site-local addresses
or 6to4 addresses for 10/8? I read in this list site-local addresses
would also be deprecated in a near future.
Final question: I read in 6to4 setup instructions that one should add
a route with ::192.88.99.1 as gateway for 2000::/3. I also read that
IANA currently has been assigned 2000::/3, so it seems to be a default
route.
However, with my setup, I can't ping6 ::192.88.99.1. I think this
is because I did absolutely nothing to support anycast addresses, how
should I? Do you have any links regarding this?
Thanks for any responses; I'm sorry if the message is confused, so
am I...
Regards,
