I have a domain and shared hosting at godaddy. I've created a subdomain and added an ipv6 proxy from sixy.ch 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?

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. – WhyNotHugo Jun 21 '12 at 01:13
