Hello everyone,
I'm testing DNS over IPv6 on a testbed and I'm confronted to an issue.
Here is my configuration: I'm working on a Red Hat Distribution (8.0) with 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 ...
The problem is, that the host command asks for an A6 record and your DNS uses AAAA records (which is correct). I use the command ipv6calc -r fec0:0:0:1::2 to reverse the ip and the do a dig xxx.ip6.arpa PTR to check the reverse delegations. Hope that gives some input to you.
