Today morning I received an email from Cloudflare team about the launch of â€œCloudflare Automatic IPv6â€³. This service makes your website compatible with IPv6 network with one click, even if your main server is still running in old IPv4 network. You might ask why I need to make my site IPv6 compatible? I will quote the content of Cloudflareâ€™s email. I hope this will make things clear and why you should be ready for IPv6.
