Hello everyone,
I'm testing DNS over IPv6 on a testbed and I'm confronted to an issue.
Here is my configuration: Bind 9.2.1.9
I've set up configuration files and the forward lookup works over IPv4 and IPv6
but the reverse lookup is only working with IPv4.
(fec0:0:0:1::2 is one of the site-local addresses of my machine (DNS server))
e.g. host fec0:0:0:1::2 gives me:
Host \[xFEC00000000000010000000000000002].ip6.arpa not found: 2(serverfail)
First I realized that even if I tried to use ip6.int suffix in the
configuration files, the message error keeps the same - Host
\[xFEC00000000000010000000000000002].ip6.arpa not found: 2(serverfail) !!!
Secondly, by sniffing with ethereal the packets, I've seen that the query is
well sent to the computer (loop back) but no response is given and then
computer tries to ask root DNS...
I'm not out of idea, may be one of you can help me ...
I post my config files.
