Does the Azure Public DNS name servers IP change?

Question

Looking to implement Azure DNS with some on-prem networking devices and they require the IP only.

Able to get the IP for the Azure DNS name servers but worried about the name servers changing IP addresses which could cause resolution issues on the network devices.

Anyone know if the Azure DNS name server IP addresses change? And if so, any guidance on this?

Thanks!

Thank you for your patience here.

I did some search internally and got to know that IP for the Azure DNS name servers can change. An alternative in this case will be to use Azure Private DNS resolver which resolves your Azure private DNS zone from on-premises, enter the IP address of the inbound endpoint into your on-premises DNS conditional forwarder. You will have to use private DNS zone in this case and establish connectivity with your on-prem using VPN or express route.

Alternate solution in this case will be to use a custom solution which can detect IP address change and take necessary actions.

Hope this help! Please feel reach out to me on teams if you need any additional information. Thank you!
