I have setup an Nginx server in a machine which have both ipv4 and ipv6 addresses. Currently, its connected to CloudFlare and only use ipv4. I have 1 ipv4 address assigned to the web server.
Now what I want is, to become fully ipv6. Then connect to CloudFlare. So, if an ipv4 user comes to the site, CloudFlare will make sure that he can visit my ipv6 only site! Does it happen like that?
What is the best way to implement ipv6 on my server? Only ipv6 or both versions? How to implement it (In CloudFlare dns and in Nginx configuration file). Please help!
