BloxOne provides DNS fallback mechanisms to ensure DNS protection for your networks in cases where your local DNS resolver is temporarily offline or when the connection from your BloxOne hosts to BloxOne Cloud is unavailable. When you enable DNS fallback, your BloxOne system will always have a functional name server to fall back to, so your DNS queries can always be resolved.

When you select the check box, the DNS queries will fall back to the root server(s) even if there are forwarders added at the DNS member level. If you cannot enable the root servers or if the root servers are not reachable, ensure that you use DNS protection by enabling Fallback Resolver when configuring the applicable DFP service, so the DNS queries will fall back to the configured server(s). For information, see Configuring DNS Forwarding Proxy Settings. |
