the command:

nslookup ipv6.google.com

doesn't work quite well. somtimes it returns an correct ipv6 address, sometimes it returns an ipv4 address. How can this happen?

[im using OpenDNS]

much thanks for help.

can you add a copy/paste of the results you are seeing? – MattB May 7 '10 at 13:43
sorry MattB, it now returns correct ipv6 addresses. I only encountered this problem in some days earlier and i didn't save the result. – deo May 10 '10 at 2:15

You might try forcing a AAAA query: 

nslookup -type=aaaa ipv6.google.com

Also keep in mind that nslookup isn't very good at what it's supposed to do.
