DNS resolution without an IP address

Is there a way to resolve DNS names without an IP address?
I know there are DNS search domains, but those only work with IP addresses.

Pritunl: Cannot use DNS search domains without setting DNS servers.

I need to resolve a DNS whose IP address is constantly changing.

That’s the problem, which is why I’m asking this question in the first place. Users need to be able to access an Azure database via VPN. Azure databases only work via DNS name. The IP address keeps changing. That’s just Microsoft.

Thx for any Help.

It will only accept IP addresses of DNS servers for this you would typically need to use the Azure DNS server IP which should be 168.63.129.16 and enable client DNS mapping which will proxy DNS requests through the Pritunl server.
