+                depending on the server's runtime configuration.
+                When enabled, the DHCP server will always add the DNS option to DHCP responses.
+                If a DNS server is not explicitly configured, the server's IP address will be used
+                as the fallback for the DNS option.
+                When disabled, the DHCP server will only include the DNS option in responses
+                if a DNS server has been explicitly configured.
+                This option will be removed in IDF v6.x
