Domain name servers (DNS) are used to translate domain names to IP addresses. If the DNS server that supports your organization is down, multiple services, such as mail servers, web sites, or proxy servers may be unavailable to the outside world.
DNS monitoring provides consistent connectivity to your websites and servers, saving you time when diagnosing DNS issues. DNS monitoring ensures your critical services are always up and running.
Device Cached. This is the default option and means the cached name server (NS) address retrieved during monitoring of a previous task (device cache) will initially be used for monitoring. If the device cache does not have the needed address, then an automatic inquiry for the address from root DNS servers will be conducted.
Non-cached. The device cache (cache of preceding tasks) will not be used, so each new execution demands a separate inquiry to DNS root servers. This is useful for ensuring uniform times since the DNS lookup will be performed each time.
TTL Cached. NS cache formed during monitoring of preceding tasks (device cache) will initially be used for monitoring. If the device cache does not have the needed address, then an automatic inquiry for the address will be conducted from the local DNS server.
External DNS Server. A specified IP address will be considered as a DNS server address and polled for NS data. For example, this is useful in situations where most of your clients use a public caching service.

When it comes to DNS errors triggered during web monitoring, it’s not typically easy to quickly identify and understand the exact issue that leads to connection errors.
Refer to our wiki, where we’ll walk you through how to fix DNS errors step-by-step.
The short answer to this is: yes. DNSSEC is a suite of extensions that improve Domain Name System (DNS) security by verifying that DNS results have not been tampered with. Enterprises can use DNSSEC to prevent attacks related to DNS spoofing, DNS cache poisoning, etc.
When DNS was developed, security was not a top priority. Because of this, when sending a request to an authoritative DNS server, the resolver cannot verify the authenticity of the response sent by name servers to clients. The resolver is only able to check if the response comes from the same IP address to which the original request was sent. DNSSEC helps verify the authenticity of DNS responses through digital signatures for DNS records. You can learn more about DNSSEC validation in this knowledgebase article.
