before all, i ask for the developers don’t treat this like a BUG but like a Feature to be improved.
I found out how do multiple subdomain from root delegated domain into dynv6, for example “example.com”
To this to work in how the service allows:
1°, create all the subdomains you will use into “My Domains”, Multiple zones types.
test1.example.com test2.example.com test3.example.com test4.example.com
2°, include the root domain, example.com, “single zone” type.
3°, add one cname record for every subdomain you have created into your root domain (example.com).
4°, if you don’t have delegate the root domain yet, just do it.
5°, Create yours zones, with yours subdomain, like myiphone.test1.example.com
