SVM DR (‑identity‑preserve ture) , can implement with (on-box) DNS Load Balancing?

Hi

Well, The question is more Microsoft oriented – but I couldn’t find a MS resource (except https://technet.microsoft.com/en-us/library/cc771640(v=ws.11).aspx   -   Understanding Zone Delegation).

NetApp relevant TR’s not saying it specifically, and I want to make sure my implementation is right:

https://www.netapp.com/us/media/tr-4523.pdf  -   DNS Load Balancing in ONTAP Configuration and Best Practices

https://library.netapp.com/ecm/ecm_download_file/ECMP12462587  - Clustered Data ONTAP 8.3 SVM Disaster Recovery Preparation Express Guide

https://library.netapp.com/ecm/ecm_download_file/ECMP12454817   - Clustered Data ONTAP® 8.3 Data Protection Guide

Is it safe to add the DR LIF ip as name server to the DNS delegation?  or that might create performance or other intermitted issues? (depends I guess how MS doing the load spread between these servers)

Should I maybe not use it on the SVM DR and just use classic  dynamic DNS?

Thanks
