DNS monitoring tool is a cloud-based scanner that constantly monitors DNS records and servers for anomalies. This tool aims to ensure that users are sent to genuine and intended website pages, instead of fakes or replicas. It alerts users about issues with the DNS servers, such as slow response times or server outages.

The tool tracks changes made in DNS records, such as SOA, MX, SRV, and NS, and compares records among primary and secondary DNS servers for any mismatch. It also ensures that users are being served from the geographically closest server.

Overall, it’s critical for all brands to ensure their DNS servers perform at their best.

Why is DNS Monitoring Important?

DNS monitoring helps businesses ensure that their users land at their intended destination after entering the correct URLs.

While users can encounter errors because of DNS misconfigurations, bad actors actively siphon off innocent users to fakes of original websites, looting them of their personal or financial details. Furthermore, other types of cyberattacks, such as DDoS, can increase the lookup times or even render a DNS server completely unreachable.

Essentially, DNS server failures, sub-par performance, or misconfigurations cause substantial losses to business reputation and associated stakeholders. Therefore, it’s important for teams to constantly monitor the performance of their DNS servers.

What is the Difference Between Website Monitoring and DNS Monitoring Software?

Website monitoring software is a tool for tracking a website’s overall health and performance. It entails a series of checks for SSL certificate, domain expiry, uptime, page speed, content accuracy, and more.

DNS monitoring, on the other hand, ensures that the domain name (ex., geekflare.com) correctly resolves to the intended IP address. Advanced DNS monitoring tools also check resolution times, compare server performance, detect misconfigurations, and offer troubleshooting guidance.

FAQs

What is the best way to check DNS records?

The best way to check DNS records depends on the frequency of tests and the tester’s technical expertise. One of the most accurate methods is checking records directly at the DNS hosting provider. For repeated checks, using DNS monitoring tools such as Site24x7 is more beneficial. Additionally, solutions like AppNeta provide comprehensive network monitoring, including DNS checks, and are best suited for enterprise use cases.

How do I monitor DNS latency?

DNS latency is the total time a DNS server takes to resolve a query. You can monitor DNS latency with DNS monitoring tools such as Dotcom-monitor or Paessler PRTG.
