DNS Monitoring

Domain Name Servers (DNS) forward visitors to the correct resources on the internet when they enter a website address or click a link. The DNS does this by turning a website name into a string of numbers. Think of it like a store location being translated into a street address. Without functional DNS servers, your website would be unavailable.

Monitoring DNS is an essential part of your website security. DNS monitoring tools check the reliability of the servers and changes in the DNS configuration.

Why is DNS Monitoring Important?

DNS monitoring will alert you if the DNS becomes unavailable, or if changes are made that you should be aware of, such as your DNS being intermittent, or hackers changing your DNS with malicious intent.
