VNET link to multiple private DNS zones

Question

1. we have a group of subscriptions, each of them has their own private DNS zone deployed with different private endpoints. One thing to highlight here is that all of these zones would have exact same name. e.g. privatelink.database.windows.net
2. we also have a management subscription with a management VNET, where our custom DNS server is located.
3. for all other subscriptions, we use that custom DNS server. but for private endpoint, we have to link this management VNET to all the existing private DNS zones
4. the issue is we can't link one VNET to multiple DNS zones with the same name. workaround here is to manually add all the DNS records together. But we really don't want it to be manually managed.

ASK: will MS consider to allow one VNET link to multiple zones with the same name? or any other workaround here would be highly appreciated.

Hello @Anonymous ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

If you're using a private endpoint in a hub-and-spoke model from a different subscription or even within the same subscription, it is recommended to link the same private DNS zones to all spokes and hub virtual networks that contain clients that need DNS resolution from the zones.

A single private DNS zone is required for this configuration. Creating multiple zones with the same name for different virtual networks would need manual operations to merge the DNS records.
This is a known limitation and can be found documented in the below article:

However, we will note your feature request and will forward this to the Product team for future improvements.

Kindly let us know if the above helps or you need further assistance on this issue.
