experimenting with A6 chains

[WOLFF]

Hello,   I am experimenting with the A6 chainning. I have a dual v6-v4 DNS server with BIND9.2.1. It supports A6 RR but the resolver does not seem to understand them. I understand that i have to run the lwresd and configure the lwresd.conf, but i have a lot of doubts about how to do this. The Bind9 documentation did not answer this doubts, so i tried changing and using the lwresd.conf that is in bind9.2.1/bin/tests........../lwresd.conf , but this did not work either.  I would be very gratefull if you point me to any documentation about how to install and configure a resolver that understand A6 chains for FreeBSD 4.5, or if you could give me any hint, regards, Martin Wolff.
