You can configure DNS zones for your DNS service. A DNS zone is a distinct portion of the domain name space in DNS.

When you configure a DNS zone, you can specify a source IP for a DNS forwarder to use when forwarding DNS queries to an upstream DNS server. If you do not specify a source IP, the DNS query packet's source IP will be the DNS forwarder's listener IP. Specifying a source IP is needed if the listener IP is an internal address that is not reachable from the external upstream DNS server. To ensure that the DNS response packets are routed back to the forwarder, a dedicated source IP is needed. Alternatively, you can configure SNAT on the logical router to translate the listener IP to a public IP. In this case, you do not need to specify a source IP.
