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?
