in order to APPLE , after 1 June all applications must support the ipv6 so i need to reconfigure my ios app. So i create a local network with ipv6. My topology is below. i configured bind 9.8 on centos A and AAAA record and PTR record.
i can query all domains on local (::1) with ipv6 like below but if other devices write dns query ip to IPV6 , it gets timeout. So requests listened with tshark and i saw that ICMPV6 cant reachable. i can ping all local IPV6 and can traceroute them.i thought it is about firewall and closed it but there is no change.
if nslookup server is configured with ipv4 , dns query can response A and AAAA results.
in named.conf , allow-query option is any and i get tutorial from [here]: http:// seoroot.com/blog/computing/systems-administration/setup-dns-server-for-ipv6-and-ipv4-queries-using-bind9-in-centos-linux.html
Here is problem that why dns query result cannot go destination , even if can ping or traceroute.
Thanks for helps and response.
