I had a site hosted on 1and1 that I moved to an Azure VM. I found that some people who have IPv6 enabled in their routers (not sure if that's the only situation but it's the one that I came across) are being sent to the site that was on 1and1.
The router I tested on had IPv6 enabled but I could still browse to sites that have only IPv4.
I had moved the site to Azure, changed the DNS, and it works perfectly but I also left the site folder on my 1and1 hosted package (I still have other sties hosted there) and that is what people are seeing.
Azure doesn't support IPv6 - they don't provide IPv6 addresses - so how can I ensure that people who have IPv6 enabled get to the correct site?
Thank you.
