Subdomain Single/Multi Zone

I am struggling a bit with the configuration of a zone including subdomains
I delegated a domain successfully and assigned a single zone to it

Now I can create A records for


The zone itself points to

How can I update these assigned ip addresse from each machine separately?

If I use I get a 404 Error
(updating works)

On the other hand i could delegate the domain as multi zone. Then I can update the subdomains like described but cannot be configured to resolve to

Am I missing something or have an error in my thinking?
(EDIT: Another possiblity would be to add NS records for the subdomains at and create zones for each subdomain, which could be updated then)


I hope this help you.
