I hope, I choose the right category here.
I set up my own webserver and wanted to make it reachable with my own domain taxi-marion.de, so I created a dynamic dns-domain taxi-marion.dynv6.net (which works fine) and set a CNAME-Entry for www.taxi-marion.de which leads to taxi-marion.dynv6.net. The main-domain taxi-marion.de is forwarded (alias) to www.taxi-marion.de.
However this doesnt work. I’m new in these things and I hope that I just forgot something or made a simple mistake. I’m grateful for every hint. Thank you very much!
