ipv6 dns resolution

[Miyone]

Hello guys. (I hope this is the right place to ask, otherwise pls. advise me accordingly.)

I have this problem on my ipv6 network and dns setup and i'll appreciate any input to help me resolve this. My question is: If i point to a subdomain (ex. ipv6.google.com), how do i resolve to its ipv6 address by default?

To explain further, if I do 'dig' with AAAA RR, it will resolve correctly as expected.

$ dig @my-dns-server ipv6.google.com AAAA +short
gives

2001:4860:c004::68

However, if i do 'ping6 ipv6.google.com', it cannot resolve the address.

Setup is as follows:

- a separate ipv6-only network
- linux dns server on the ipv6 network that acts as dns forwarder (with local ipv4 interface) to the ipv4 network
- linux dns server in the ipv4 network running bind 9.6.1-P1

- client is a mac os x 10.6 (if relevant)

There must be something wrong with my setup. Any suggestions on how to approach this? TIA.

All the best,

Try the dig without @my-dns-server. That'll give you a better baseline
comparison to how ordinary commands like "ping6" resolve DNS from that box.

Also, if you have control of my-dns-server, turn on query logging (if
not already turned on) and see if you're actually getting AAAA queries
for ipv6.google.com from the client.

Alternatively, fire up a sniffer or network tracer of some kind.
