I have a domain and shared hosting at godaddy. I've created a subdomain and added an ipv6 proxy from in my aaaa records. Nov I have IPv4 a v6 connectivity too, but i want to block access from IPv4 adresses to get an Ipv6 only subdomain. How can I force an IPv6 connection? Already asked at godaddy support but they just paste general answers from the FAQ.

Edit: Can I block all IPv4 connections in .htaccess file and force the client to connect with IPv6 if he has both protocols installed?

GoDaddy is also just a poor quality provider, and often doesn't support advanced features. – Stefan Lasiewski Jan 12 '12 at 18:48
Get native ipv6, and get rid of proxies/tunnels. Once you've done that, you need to set AAAA records, and delete the A records. – Hugo Jun 21 '12 at 1:13

You want the IPv6 subdomain to only have the AAAA record, no A record. This should be configurable in the DNS zone editor at Godaddy, even though I have never used Godaddy myself.

Tried that, but this proxy just tunnels the ipv6 traffic to ipv4, when I deleted the A record, the domain went down. – Lahon Zeravosch Jan 12 '12 at 16:30
@LahonZeravosch: Just a sanity check, but are you sure that the AAAA record existed after you deleted the A record? The GoDaddy domain tool might be doing something wrong with the AAAA record. – Stefan Lasiewski Jan 12 '12 at 18:59
Yes, the AAAA record is there, but as I said, this is not native ipv6, just a tunnel. The subdomain loads if i'm using http://[IPv6example]/ but just if the A record is added too. – Lahon Zeravosch Jan 12 '12 at 19:32
If it's not native ipv6, but just a tunnel, you can't expect clients to user pure native ipv6. It doesn't make sense. – Hugo Jun 21 '12 at 1:13
