Hi Juha and Anand,
Can you clarify: "What if we already have some static "IPv6 in
IPv4" tunnels configured from the operator's network to, say, IPv6 internet /
6bone and there is IPv6 connection to node B?"
My small experience shows that configuring static tunnels becomes quickly
boring. I would prefer a 6to4-based solution. But it seems that security issues
are remaining... I have to check that.

Anand,
I assume that this is a very common problem /
environment in initial IPv6 deployment, i.e. two separate IPv6 islands
connected by IPv4 network using "IPv6 in IPv4" tunneling and solutions have
already been thought by several (DNS) experts.
What if we already have
some static "IPv6 in IPv4" tunnels configured from the operator's network to,
say, IPv6 internet / 6bone and there is IPv6 connection to node B?
I am
very happy to receive more comments on this
issue.
Thanks,
-Juha-

Subject: 3gpp scenario 2
hi huha,
i was just
wondering about the scenario in which 2 IPV6 UEs communicate over
an IPV4
network. In this scenario won't initial DNS resolution be a very
difficult
job (if not impossible)?
If you have not understood my question read this
example:
Let Host A be on IPV6 netork X and Host B on IPV6 network Y. Now,
if A makes
a DNS query ("A") for B, none of the name resolvers in network X
will have
an entry for B . How will this query finally reach network Y,
assuming all
intermediate routers are IPV4 only? Will A have to explicitly
tunnel this
request to network Y? I am also assuming that DNS servers in
the IPV4
internet don't support "AAAA".
regards
Anand
