Question Re: Zone Delegation + A Record (Windows Server)

Is it possible (or even proper) to host an A record while simultaneously delegating out that subdomain/zone to a 3rd party? Would the A Record for that have to be configured at the 3rd party?

Use case:

Host a service endpoint at srv.example.com while operating dyndns on zone srv.example.com for N nodes?

Example architecture:

• srv.example.com <= A Record to a valid IP (Reported by NS1)
• srv.example.com <= Zone record delegated to NS2/NS3
• node1.srv.example.com <= A Record to a valid IP (repored by NS2/NS3)
• node2.srv.example.com <= A Record to a valid IP (repored by NS2/NS3)
• …

This would be configured on Windows Server DNS. I know that I can create it without error, but is it valid? Bad Practice? etc.

Thanks!!
