How to set up custom domain

Hi there, I basicly dont know anything about domains.
Could someone tell me how i get a custom domain to work?
I bought the domain on alldomains.hosting, there i changed the Nameserver to the three of dynv6. In “My Domains” the status is delegated and details says that the results are valid.
But it doesnt work. Are there any special dns-settings that i should set on alldomains.hosting? Or do I even need the dns-service of alldomains.hosting?
I got it working with a dynv6.net adress, but not with my own domain.
Thanks in advance :slight_smile:
