Best DNS Server Monitoring and Troubleshooting Tools and Software

DNS monitoring is no less important than infrastructure monitoring. DNS monitoring allows you to see the quality of your connection between authoritative name servers and local recursive servers. Measuring the response time between these servers indicates the strength of your connection.

Monitoring DNS servers allow you to check for signs of poor performance like latency or even outright disconnections. Using a DNS server monitoring tool will allow you to see when your connection is failing you and enable you to step in. In particular, a DNS server monitoring tool with an alerts function will notify you if your connection is performing poorly. This is very useful for cutting down your manual workload.

DNS Server FAQs

Why is DNS monitoring important?

DNS lies at the heart of your addressing system. If DNS is not kept up to date, applications running on your network that rely on hostnames rather than IP addresses will stop working. On the web, DNS is even more vital. Without correct DNS entries, your website ceases to exist.

What is the most popular DNS server software available?

The most widely used DNS server system is called BIND. The current version of this system is BIND 10 and it is open source. The BIND service is built into most versions of Unix and Linux.
